In this blog we will learn how to add splash window in tkinter. To start this first we will know about splash window. What is splash window ? A splash window or screen is a particular window or screen on a website or piece of software that displays while the application or other item is loading. After the load is complete, the user is generally taken to another more functional screen. The splash screen is generally just a display screen to orient users and give them something to look at while hardware is working to present the software to them. A splash screen is also known as a start screen or startup screen. Here we add small code which is written in python tkinter : First import all library in python main file : Code of splash.py #ImportLibrarHere from tkinter import * from tkinter import ttk import time import datetime from PIL import ImageTk,Image import os import sqlite3 from tkinter import messagebox #SplashScreen sroot = Tk() sroot.minsize(height=200,width=300) sroot.title("Splash window") sroot.configure() spath = "images/mypic.png" simg = ImageTk.PhotoImage(Image.open(spath)) my = Label(sroot,image=simg) my.image = simg my.place(x=0,y=0) Frame(sroot,height=516,width=5,bg='black').place(x=520,y=0) lbl1 = Label(sroot,text="Welcome to Codersarts",font='Timesnewroman 20 ',fg='blue') lbl1.config(anchor=CENTER) lbl1.pack(padx = 100, pady = 100) #MainScreen def mainroot(): root = Tk() root.geometry('1080x500') root.minsize(width=1080,height=550) root.maxsize(width=1080,height=550) root.configure(bg='white') root.title("main window") . . . #AddWindowFunctionalityHere(like widgets, etc) . . . #EndOfMainWindow # After this call the main window here def call_mainroot(): sroot.destroy() mainroot() sroot.after(3000,call_mainroot) #TimeOfSplashScreen mainloop() If you want to read other codersarts arts top rated blog then click here 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.

Database is collection of data in a most efficient way so that insertion, update ,deletion ,and selection. To perform most common operation there are lots of database available over internet to fulfill different purpose. Database is important part of our project and as a software engineer or developer or even if you are computer science student you must know as much so that you can perform basic and medium level query easily. Database schema is refer to high level data collection view not details view. Like suppose you are going to design database schema of colleges then database schema includes all table with fields name , key attribute, and relation between tables. You may think database schema as ERD but not exactly same because in ERD diagram you mention each attribute, derived attribute, relation with diagonal same like that but this is not included in database schemas. Here is official definition of Database schema- The term "schema" refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases). The formal definition of a database schema is a set of formulas (sentences) called integrity constraints imposed on a database. Here is some common tool for Database Diagram Design Microsoft Visio dbdiagram.io Draw.io

Hi, In this blog we will learn all about regular expression. Now a day regular expression is include most of project framework to connect urls so its important know all about regular expressions. So to solve this and provide best help here we will try to give complete study package of regular expression with example so that you can apply it easily at any where in python. In python there are 14 metacharacters which used in reg. which we listed below: And use some Unicode string patterns to find string as per these basis : \d : Matches any decimal digit; this is equivalent to the class [0-9]. \D : Matches any non-digit character; this is equivalent to the class [^0-9] \s : Matches any whitespace character; this is equivalent to the class [ \t\n\r\f\v]. \S : Matches any non-whitespace character; this is equivalent to the class [^ \t\n\r\f\v]. \w : Matches any alphanumeric character; this is equivalent to the class [a-zA-Z0-9_]. \W : Matches any non-alphanumeric character; this is equivalent to the class [^a-zA-Z0-9_]. Let's Start with some examples First need to import it by using this : >>> import re Here list some important methods which used to search string patterns compile() split() sub() subn() escape() search() match() findall() compile() We can combine a regular expression pattern into pattern objects, which can be used for pattern matching. It also helps to search a pattern again without rewriting it. split() This will split at every space that is followed by a string of upper-case letters which end in a word-boundary. sub() The re.sub() function in the re module can be used to replace substrings. The syntax for re.sub() is re.sub(pattern,repl,string). That will replace the matches in string with repl. Example: subn() This function is similar to sub() in all ways except the way in which it provides the output. It returns a tuple with count of total of all the replacements as well as the new string. Syntax: escape() Return string with all non-alphanumerics backslashes; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it. Example: search() Scan through string looking for the first location where the regular expression pattern produces a match, and return a corresponding match object. Return None if no position in the string matches the pattern; note that this is different from finding a zero-length match at some point in the string. Example: match() The match function is used to match the RE pattern to string with optional flags. In this method, the expression "w+" and "\W" will match the words starting with letter 'g' and thereafter, anything which is not started with 'g' is not identified. Example: findall() The expression re.findall() returns all the non-overlapping matches of patterns in a string as a list of strings.

Definition Sandboxing is security mechanism which is used in computer security. Sandboxing technology main purpose is to separate system failures or software vulnerabilities from spreading and execute untested or untrusted programs or code, possibly from unverified or untrusted third parties, suppliers, users or websites, without risking harm to the host machine or Operating System. Common Example of sandboxing is Online Programming compiler Like HackerRank HackerEarth Codeforces Codechef A sandbox typically provides a tightly controlled set of resources for guest programs to run in, such as scratch space on disk and memory. Network access, the ability to inspect the host system or read from input devices are usually disallowed or heavily restricted. Scratch space is space on the hard disk drive that is dedicated for only temporary storage. It cannot be used to permanently back up files. Scratch disks can be set to erase all data at regular intervals so that the disk space is left free for future use. The management of scratch disk space is typically dynamic, occurring when needed. A sandbox is implemented by executing the software in a restricted operating system environment, thus controlling the resources (for example, file descriptors, memory, file system space, etc.) that a process may use.It provides an extra layer of security that prevents malware or harmful applications from negatively affecting your system.

What is python Introspection ? Introspection used to self examination of python objects Properties and type at the runtime. By using introspection, we can dynamically inspect Python objects. List of important Introspection dir() type id() sys hasattr() issubclass() callable() dir() It returns a sorted list of attributes and methods belonging to an object. syntax: >>> dir(()) Output: ['__add__', '__class__', '__contains__', '__delattr__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'count', 'index'] Here we use dir() with different ways: obj = classname() print(dir(obj)) print(dir([])) print(dir({})) print(dir(1)) print(dir()) print(dir(len)) print(dir(sys)) print(dir("String")) Add modules in dir() In dir() add modules using import >>> import math, os >>> dir() It import two module, math and os in dir() type() It returns the type of an object. Example: #!/usr/bin/python3 # typefun.py import sys def function(): pass class MyClass(object): def __init__(self): pass o = MyClass() print(type(1)) print(type("")) print(type([])) print(type({})) Output: id() function It returns a special id of an object. Example: #!/usr/bin/python3 # idfun.py import sys def function(): pass class MyClass(object): def __init__(self): pass o = MyClass() print(id(1)) print(id("")) print(id({})) print(id([])) Output: 10914368 139696088742576 139696087935944 139696065155784 sys module It provides access to system specific variables and functions used or maintained by the interpreter and to functions that interact strongly with the interpreter. First import the sys module: >>> import sys If you want to check which platform is running currently then use this >>> sys.platform It return the system python where python script folder exists: >>> sys.path hasattr() function It checks if an object has an attribute callable() function It checks if an object is a callable object (a function).
