strip():
The strip() removes characters from both left and right based on the argument (a string specifying the set of characters to be removed).
Syntax:
string.strip(['character'])
Ex.
string = ' naveen kumar rajput '
# white space remove
print(string.strip())
# remove nav from string at start
print(string.strip('nav'))
split():
The split() method breaks up a string at the specified separator and returns a list of strings.
The syntax of split() is :
str.split(separator[,maxsplit])
Ex.
text= "naveen kumar"
# split at space found
print(text.split())
output:
['naveen', 'kumar']
name = 'naveen, kumar, rajput'
# split at (,) found
print(text.split(','))
output:
['naveen', 'kumar', 'rajput']
format() in python:
The string format() method formats the given string into a nicer output in Python.
format() method takes any number of parameters. But, is divided into two types of parameters:
Positional parameters - list of parameters that can be accessed with index of parameter inside curly braces {index}
Keyword parameters - list of parameters of type key=value, that can be accessed with key of parameter inside curly braces {key}
Ex.
Basic format() Examples:
print("Hello {}, your balance is {}.".format("naveen", 16.8))
print("Hello {name}, your balance is {blc}.".format(name="naveen", blc=16.8))
print("The float number is:{:f}".format(123.456))
print("The float number is:{:3f}".format(123.456))
