What is data Wrangling? Data Wrangling is the process of converting data from the initial format to a format that may be readable and better for analysis. Here we use the below data set : https://archive.ics.uci.edu/ml/machine-learning-databases/autos/imports-85.data Import pandas Open Jupyter notebook or any online jupyter notebook editor and import pandas- import pandas as pd import matplotlib.pylab as plt Reading the data and add header filename = "https://s3-api.us-geo.objectstorage.softlayer.net/cf-courses-data/CognitiveClass/DA0101EN/auto.csv" headers = ["symboling","normalized-losses","make","fuel-type","aspiration", "num-of-doors","body-style", "drive-wheels","engine-location","wheel-base", "length","width","height","curb-weight","engine-type", "num-of-cylinders", "engine-size","fuel -system","bore","stroke","compression-ratio","horsepower", "peak-rpm","city-mpg","highway-mpg","price"] Read CSV df = pd.read_csv(filename, names = headers) Show data in tabular form df.head() Data display in tabular form and you will face some challenges like this- identify missing data deal with missing data correct data format Identify and handle missing values Identify missing values Convert "?" to NaN Missing data comes with the question mark "?". We replace "?" with NaN (Not a Number) Example: import numpy as np # replace "?" to NaN df.replace("?", np.nan, inplace = True) df.head(5) It set NaN at first five index row where "?" is presented. How to detect missing data: There are two method used to detect missing data. .isnull() - Return true at the place of missing data and other place return false. .notnull() - Return true at the placed data and false at missing data place. Example: mis_value = df.isnull() mis_value.head(5) Count missing value -In columns Using for loop: Example: Write this for loop and find result for column in mis_value .columns.values.tolist(): print(column) print (mis_value [column].value_counts()) print("") How we will work with missing data Drop data drop the whole row- Let suppose any value is necessary like price but it is missing at any row then we remove whole row. drop the whole column - let we suppose if price is missing at any column then it reason of delete whole column because price is necessary for data science to calculate price. Replace data replace it by mean replace it by frequency - replace as per frequency for example- 84 % is good, and 16% bad, then 16% remove by good. replace it based on other functions Calculate the average of any column Example avg= df["column name"].astype("float").mean(axis=0) print("Average of column name:", avg) Replace "NaN" by mean value - of any column Example df["column_name"].replace(np.nan, avg, inplace=True) Calculate the mean value - of any column Example avg=df['column_name'].astype('float').mean(axis=0) print("Average of column_name:", avg) Replace NaN by mean value Example df["column_name"].replace(np.nan, avg, inplace=True) How count each column data separately Use value_counts() function Example: df['column_name'].value_counts() Output like this: let suppose column_name is qualification then count each qualification with name. mca 78 bca 45 Calculate for us the most common (max) automatically df['column_name'].value_counts().idxmax() Output: mca 78 Replace NaN by most frequent Example df["column_name"].replace(np.nan, "four", inplace=True) All NaN replace by most frequent- by "four" Drop whole row with NaN in "Column_name" column Let suppose column_name is "price" df.dropna(subset=["price"], axis=0, inplace=True) # reset index, because we dropped two rows df.reset_index(drop=True, inplace=True) Correct data format In Pandas, we use .dtype() to check the data type .astype() to change the data type Show list of data type: Use this syntax to list data type - syntax: df.dtypes How to convert data type in proper format There are different type of data format used - Syntax: df[["column1", "column2"]] = df[["column1", "column2"]].astype("float") df[["column3"]] = df[["column3"]].astype("int") df[["column4"]] = df[["column4"]].astype("float") df[["column5"]] = df[["column5"]].astype("float") Again check it by using following - It show list so that you can verify that data type is change or not Syntax: df.dtypes Data Standardization What is Standardization? Standardization is the process of transforming data into a common format which allows the researcher to make the meaningful comparison. Example Transform mpg to L/100km The formula for unit conversion is L/100km = 235 / mpg First go through the data to verify it by using this syntax- Syntax: df.head() Example: Convert mpg to L/100km by mathematical operation df['city-L/100km'] = 235/df["city-mpg"] It add new column city-L/100km after change the value of column city-mpg # check your transformed data df.head() Data Normalization Why normalization? Normalization is the process of transforming values of several variables into a similar range. Example: # replace (original value) by (original value)/(maximum value) df['length'] = df['length']/df['length'].max() df['width'] = df['width']/df['width'].max() Binning Why binning? Binning is a process of transforming continuous numerical variables into discrete categorical 'bins', for grouped analysis. Indicator variable (or dummy variable) What is an indicator variable? An indicator variable (or dummy variable) is a numerical variable used to label categories. They are called 'dummies' because the numbers themselves don't have inherent meaning. Why we use indicator variables? So we can use categorical variables for regression analysis in the later modules.

Learn how to analyze data using Python. This blog will take you from the basics of Python to exploring many different types of data. You will learn how to prepare data for analysis, perform simple statistical analyses, create meaningful data visualizations, predict future trends from data, and more! 1- You will learn how to: 2- Import data sets 3- Clean and prepare data for analysis 4- Manipulate pandas DataFrame 5- Summarize data Python itself does not include vectors, matrices, or dataframes as fundamental data types. As Python became an increasingly popular language, however, it was quickly realized that this was a major short-coming, and new libraries were created that added these data-types (and did so in a very, very high performance manner) to Python. The original library that added vectors and matrices to Python was called numpy. But numpy, while very powerful, was a no-frills library. You couldn’t do things like mix data-types, label your columns, etc.. To remedy this shortcoming a new library was created – built on top of numpy – that added all the nice features we’ve come to expect from modern languages: pandas. Creating A DataFrame in Pandas: Method 1: import pandas as pd dframe = pd.DataFrame({ "c1": [1, "Ashish"], "c2": [2, "Sid"]}) print(dframe) Output: Method 2: # taking index and column values import pandas as pd dframe = pd.DataFrame([[1,2],["Ashish", "Sid"]], index=["r1", "r2"], columns=["c1", "c2"]) print(dframe) Output: Importing Data with Pandas: import pandas as pd df=pd.read_csv(" csvfile.csv") # Prints the first 5 rows of a DataFrame as default df.head() # Prints no. of rows and columns of a DataFrame df.shape

Tkinter Tutorial Hi Everyone! Welcome to my Course Python Tkinter Tutorial In this course, we are going to learn how to do GUI in python. I am a python developer for a long time, and I’m so excited to share my knowledge of this awesome programming Language. This course is designed for both beginner and professional, and also helpful for everyone who wish to learn the GUI Programming in Python Tkinter. I hope you’ll join me on this journey to learn Python with the python: Getting started courses at CodersArts. In this series of python learning. We will discuss the following topics What is a Graphical User Interface (GUI) in Python? Libraries use in Python Tkinter What is Tkinter? Fundamentals of Tkinter Using Python Tkinter Widgets in Python Geometry Management in Python Organization of Layouts and Widgets in Python Tkinter Binding Functions in Python What is a Graphical User Interface (GUI) in Python? Stands for "Graphical User Interface" and is pronounced "gooey." It is a user interface that includes graphical elements, such as windows, icons and buttons. The term was created in the 1970s to distinguish graphical interfaces from text-based ones, such as command line interfaces. However, today nearly all digital interfaces are GUIs. The first commercially available GUI, called "PARC," was developed by Xerox. It was used by the Xerox 8010 Information System, which was released in 1981. After Steve Jobs saw the interface during a tour at Xerox, he had his team at Apple develop an operating system with a similar design. Apple's GUI-based OS was included with the Macintosh, which was released in 1984. Microsoft released their first GUI-based OS, Windows 1.0, in 1985. If you want to read more about Graphical Use Interface than go to the this link Python Libraries To Create Graphical User Interfaces Top python Libraries which is use by most of GUI developer is: Kivy Python QTwxPython Tkinter To read basic about these Libraries first we know about "Tkinter". What is Tkinter? Tkinter is an inbuilt Python libraries used to create simple GUI apps. It is the most commonly used module for GUI apps in the Python. To understand it clearly first we will see working of small code in which we will print hello world: Example: """Hello World application for Tkinter""" from tkinter import * from tkinter.ttk import * root = Tk() label = Label(root, text="Hello World") label.pack() root.mainloop() First line used to import module tkinter from python library In second line tkinter.ttk used to import ttk library with tkinter to add extra features. pack() used to pack the content so user can see it. The last line calls the mainloop function. This function calls the endless loop of the window, so the window will wait for any user interaction till we close it. Tkinter Widgets Widgets are something like elements. There are different types of widgets which used in Tkinter Label Widget Button Widget Entry Widget Radiobutton Widget Radiobutton Widget (Alternate) Checkbutton Widget Scale Widget: Horizontal Scale Widget: Vertical Text Widget LabelFrame Widget Canvas Widget Listbox Widget Menu Widget OptionMenu Widget Here below we discuss complete details about all widgets- how will use it and how it works? Label Widget A Label widget shows text to the user. Labels are used to create texts and images and all of that: Example: import tkinter parent_widget = tkinter.Tk() label_widget = tkinter.Label(parent_widget, text="A Label") label_widget.pack() tkinter.mainloop() Output: Button Widget To add a button in your application, this widget is used. Example: import tkinter window = tkinter.Tk() button_widget = tkinter.Button(window,text="A Button") button_widget.pack() tkinter.mainloop() Output: Entry Widget An Entry widget gets text input from the user. Example: import tkinter window = tkinter.Tk() entry_widget = tkinter.Entry(window) entry_widget.insert(0, "Type your text here") entry_widget.pack() tkinter.mainloop() Output: Radio button Widget A Radiobutton lets you put buttons together, so that only one of them can be clicked. If one button is on and the user clicks another, the first is set to off. Example: import tkinter window = tkinter.Tk() v = tkinter.IntVar() v.set(1) # need to use v.set and v.get to set and get the value of this variable radiobutton_widget1 = tkinter.Radiobutton(window,text="Radiobutton 1",variable=v,value=1) radiobutton_widget2 = tkinter.Radiobutton(window,text="Radiobutton 2",variable=v, value=2) radiobutton_widget1.pack() radiobutton_widget2.pack() tkinter.mainloop() Output: Radiobutton Widget -Alternate You can display a Radiobutton without the dot indicator Example: import tkinter window = tkinter.Tk() v = tkinter.IntVar() v.set(1) radiobutton_widget1 = tkinter.Radiobutton(window, text="Radiobutton 1", variable=v, value=1, indicatoron=False) radiobutton_widget2 = tkinter.Radiobutton(window, text="Radiobutton 2", variable=v, value=2, indicatoron=False) radiobutton_widget1.pack() radiobutton_widget2.pack() tkinter.mainloop() Output: Checkbutton Widget A Checkbutton records on/off or true/false status Example: import tkinter window = tkinter.Tk() checkbutton_widget = tkinter.Checkbutton(window, text="Checkbutton") checkbutton_widget.select() checkbutton_widget.pack() tkinter.mainloop() Output: Scale Widget: Horizontal Use a Scale widget when you want a slider that goes from one value to another. Example: import tkinter window = tkinter.Tk() scale_widget = tkinter.Scale(window, from_=0, to=100, orient=tkinter.HORIZONTAL) scale_widget.set(25) scale_widget.pack() tkinter.mainloop() Output: Scale Widget: Vertical A Scale widget can be vertical (up and down). Example: import tkinter window = tkinter.Tk() scale_widget = tkinter.Scale(window, from_=0, to=100, orient=tkinter.VERTICAL) scale_widget.set(25) scale_widget.pack() tkinter.mainloop() Output: Text Widget in Python Tkinter Use to show large areas of text. Example: import tkinter window = tkinter.Tk() text_widget = tkinter.Text(window, width=20, height=3) text_widget.insert(tkinter.END, "Text Widgetn20 characters widen3 lines high") text_widget.pack() tkinter.mainloop() Output: LabelFrame Widget The LabelFrame acts as a parent widget for other widgets, displaying them with a title and an outline. LabelFrame has to have a child widget before you can see it. Example: import tkinter window = tkinter.Tk() labelframe_widget = tkinter.LabelFrame(window, text="LabelFrame") label_widget=tkinter.Label(labelframe_widget, text="Child widget of the LabelFrame") labelframe_widget.pack(padx=10, pady=10) label_widget.pack() tkinter.mainloop() Output: Canvas Widget You use a Canvas widget to draw on. It supports different drawing methods. Example: import tkinter window = tkinter.Tk() canvas_widget = tkinter.Canvas(window,bg="blue",width=100,height= 50) canvas_widget.pack() tkinter.mainloop() Output: Listbox Widget Listbox lets the user choose from one set of options or displays a list of items. Example: import tkinter window = tkinter.Tk() listbox_entries = ["Entry 1", "Entry 2", "Entry 3", "Entry 4"] listbox_widget = tkinter.Listbox(window) for entry in listbox_entries: listbox_widget.insert(tkinter.END, entry) listbox_widget.pack() tkinter.mainloop() Output: Menu Widget The Menu widget can create a menu bar. Example: import tkinter window = tkinter.Tk() def menu_callback(): print("I'm in the menu callback!") def submenu_callback(): print("I'm in the submenu callback!") menu_widget = tkinter.Menu(window) submenu_widget = tkinter.Menu(menu_widget, tearoff=False) submenu_widget.add_command(label="Submenu Item1", command=submenu_callback) submenu_widget.add_command(label="Submenu Item2", command=submenu_callback) menu_widget.add_cascade(label="Item1", menu=submenu_widget) menu_widget.add_command(label="Item2", command=menu_callback) menu_widget.add_command(label="Item3", command=menu_callback) window.config(menu=menu_widget) tkinter.mainloop() Output: OptionMenu Widget The OptionMenu widget lets the user choose from a list of options Example: import tkinter window = tkinter.Tk() control_variable = tkinter.StringVar(window) OPTION_TUPLE = ("Option 1", "Option 2", "Option 3") optionmenu_widget = tkinter.OptionMenu(window,control_variable, *OPTION_TUPLE) optionmenu_widget.pack() tkinter.mainloop() Output: Geometry Management in Python Tkinter possess three layout managers. pack grid place Example import tkinter as tk root = tk.Tk() w = tk.Label(root, text="Red Sun", bg="red", fg="white") w.pack(fill=tk.X) w = tk.Label(root, text="Green Grass", bg="green", fg="black") w.pack(fill=tk.X) w = tk.Label(root, text="Blue Sky", bg="blue", fg="white") w.pack(fill=tk.X) tk.mainloop() Output: Binding Function in python It used to bind the event by mouse or keyboard to perform specific action Example: #!/usr/bin/python3 # write tkinter as Tkinter to be Python 2.x compatible from tkinter import * def hello(event): print("Single Click, Button-l") def quit(event): print("Double Click, so let's stop") import sys; sys.exit() widget = Button(None, text='Mouse Clicks') widget.pack() widget.bind('', hello) widget.bind('', quit) widget.mainloop() Output: List of Other Codersarts Assignment Expert Help Services Computer science Assignment help Python Programming Help Data Structures Assignment Help JAVA Assignment Help VB NET Development C++ Assignment Help C Programming Assignment Help SQL Homework Help Database Assignment Help HTML Assignment Help JavaScript Assignment Help Node js Assignment Help C# Assignment Help Android App Assignment Help MongoDB Assignment Help If you like Codersarts blog and looking for Programming Assignment Help Service,Database Development Service,Web development service,Mobile App Development, Project help, Hire Software Developer,Programming tutors help and suggestion  you can send mail at contact@codersarts.com.

There are many such programming languages in the market and what makes Python all the more different from others? Well, the answer is that Python has a focus on readability, coherence and its software quality sets it apart from others. The code of Python can be easily read and understood, even if someone hasn’t written the program. On the other hand, Python has lesser code to be written, unlike other programming languages such as C, C++ or Java. This means that there is less of coding and less of debugging. This makes the life of a programmer much easy. Also, the portability of the program needs to be mentioned. Python can easily run on all major computer platforms without the need to rewrite the whole code. Python also offers numerous options for coding portable graphical user interfaces, databases access programs, web-based systems and more. All of this is due to the presence of a large collection of prebuilt standard library. Python is also capable of a variety of integrations. You can easily use C and C++ libraries, can integrate with Java and .NET components. Design and Structure of Python The design of the language has been close to following a natural and a small set of core concepts with consistent interaction. This makes the language easy to learn, remember and implement. To be simpler, Python follows a very minimalistic approach in the syntax department. In essence, Python helps in doing more work in less time and with less effort. Use of Python Python can be used to accomplish systems programming. With Python, it is relatively easy to develop system-administrative tools and utilities. Python can use GUIs. Its simplicity and turnaround makes it an ideal GUI developer. Python can also be very helpful in developing internet scripting. It can run a variety of programs both on client and server sides. Apart from these, Python can be useful in database programming as well. Python can interface with various database systems such as Sybase, Oracle, Informix, ODBC, MySQL, SQLite, etc. Features of python Free and open-source - Learning python do not requires you to pay anything. You are free to use and distribute or can even make changes to its source code. Portability - Python is platform friendly.

Python GUI Assignment with Tkinter Tk/Tcl has long been an integral part of Python. It provides a robust and platform independent windowing toolkit, that is available to Python programmers using the tkinter package, and its extension, the tkinter.tix and the tkinter.ttk modules. The tkinter package is a thin object-oriented layer on top of Tcl/Tk. To use tkinter, you don’t need to write Tcl code, but you will need to consult the Tk documentation, and occasionally the Tcl documentation. tkinter is a set of wrappers that implement the Tk widgets as Python classes. In addition, the internal module _tkinter provides a thread safe mechanism which allows Python and Tcl to interact. Tkinter's chief virtues are that it is fast, and that it usually comes bundled with Python. Although its standard documentation is weak, good material is available, which includes: references, tutorials, a book and others. tkinter is also famous for having an outdated look and feel, which has been vastly improved in Tk 8.5. Nevertheless, there are many other GUI libraries that you could be interested in. We offer Python GUI Programming,Python Programming Assignment help & Python Programming Homework help.

What is Directory in Python? A directory or folder is a collection of files and sub directories. Python has the os module. which provides us with many useful methods to work with directories (and files as well). Get Current Directory Use command : >>>getcwd() Example: >>> import module >>>os.getcwd() Output: 'C:\\Program Files\\Py...' Use print() to escape extra backspace. Example: >>> print(os.getcwd()) Output: C:\Program Files\PyScripter Changing Directory We can change the current working directory using the chdir() method. Example: >>> os.chdir('C:\\Python33') >>> print(os.getcwd()) Output: C:\Python33 List Directories and Files Use method: >>>listdir() Example: >>> os.listdir() Output: ['DLLs','Doc','include','Lib','libs',... ] Create New Directory Use method >>> os.mkdir('test') Renaming a Directory or a File The rename() method can rename a directory or a file. >>> os.listdir() Output: ['test'] >>> os.rename('test','new') #rename "test" into "new" Removing Directory or File A file can be removed (deleted) using the remove() method. rmdir() used to remove empty directory. Example: >>> os.remove('file.txt') Hope you understand the all the concept of file or directory.

Generators are simple functions which return an iterable set of items, one at a time, in a special way. If the body of a def contains yield, the function automatically becomes a generator function. Once the generator's function code reaches a "yield" statement, the generator yields its execution back to the for loop, returning a new value from the set. The generator function can generate as many values (possibly infinite) as it wants, yielding each one in its turn. Example 1: Program to print random number form 1 to 3. def simpleGen(): yield 1 yield 2 yield 3 # Driver code to check above generator function for value in simpleGen(): print(value) Output: 1 2 3 Example 2: Program to print random number from 1 to 40. import random def lottery(): # returns 6 numbers between 1 and 40 for i in range(6): yield random.randint(1, 40) # returns a 7th number between 1 and 15 yield random.randint(1,15) for random_number in lottery(): print("And the next number is... %d!" %(random_number)) If you like Codersarts blog and looking for Assignment help,Project help, Programming tutors help and suggestion  you can send mail at contact@codersarts.com.

It is a collection type which can store elements of different data types but doesn’t index them in a particular order. It look likes mathematics set. Properties Of A Set: A Python Set has the following properties: The elements don’t have a specific order, hence, shall exist in a random style. Each item is unique in a Set and therefore, can’t have duplicates. The elements are immutable and hence, can’t accept changes once added. A set is itself mutable and allows addition or deletion of items. Also, remember, the elements can be of any types such as an integer, a float, a tuple, or strings, etc. The only exception with a Set is that it can’t store a mutable item such as a list, a set or a dictionary. Example: Create s set of numbers py_set_num = {3,7,11,15} print(py_set_num ) Executing the above code will return the following output. Use with multiple format data. Example: py_set_num = {3, 7, (1,2), "11", 1.1} print(py_set_num ) How To Modify A Set In Python? In this add() which adds a single element and the update() which can add more than one item. The update() method can even accept tuples, lists, strings or other sets as an argument. However, duplicate elements will automatically get excluded. Example: add() py_set_num = {3,7,11,15} py_set_num.add(99) print("The value of new set is" , py_set_num ) Example:Update() py_set_num = {3,7,11,15} py_set_num.update(10,15,20) print("The value of new set is" , py_set_num ) If you like Codersarts blog and looking for Programming Assignment Help Service,Database Development Service,Web development service,Mobile App Development, Project help, Hire Software Developer,Programming tutors help and suggestion  you can send mail at contact@codersarts.com. #python #pythonlist #pythonprogramming #pythontutorial #pythonproject

Learning Objectives: To understand the concept of Class and Object. To identify classes and their fields/methods from a problem statement. To understand overloading methods including class constructors. To generate random numbers with the Random class. To write your own testing cases to test your program. To use debugger for debugging your Java program. To use file output to write data to a CSV (Comma Separated Values) file Problem Statement You are required to write a stock price simulator, which simulates a price change of a stock. When the program runs, it should do the following:  Create a Stock class which must include fields: name, symbol, currentPrice, nextPrice, priceChange, and priceChangePercentage.  The Stock class must have two constructor: a no-argument constructor and a constructor with four parameters that correspond to the four fields. o For the no-argument constructor, set the default value for each field such as:  Name: Microsoft  Symbol: MSFT  currentPrice: 46.87  nextPrice: 46.87 o For the argument constructor, set the value of four fields based on the arguments.  The Stock class must have accessors and mutators for all of its fields.  The setter methods must protect a user from setting the currentPrice/nextPrice into negative number. You can set the values to 0 if a user tries to change them to negative values.  The Stock class should have a SimulatePrice() method, which increases or decreases the currentPrice by 0 - 10% randomly, such as 0.56% and 9.65%.  The main program will ask user to enter a name, symbol, current price of a stock. Then, it simulates the prices for next 30 days. It displays the prices for the next 30 days on the console and to a file named output.csv, instead of .txt. CSV (Comma Separated Values) file format is very popular because it can be opened in Microsoft Excel. For more information about CSV, you can read the following article online: o https://www.computerhope.com/issues/ch001356.htm  If a user enters “NONE”, “NA”, 0.0 for name, symbol, current price Input This program requires that you read in the following data values:  A stock’s name, symbol, and current price. o E.g., Microsoft Corporation, MSFT, 45.87. You will use interactive I/O in this program. All of the input must be validated if it is needed. You can assume that for a numeric input value, the grader will enter a numeric value in the testing cases. Output Your program should display the stock’s name, symbol, current price, next price priceChange priceChangePercentage for each day on the console and write to a CSV file.
