Python String Concatenation & Other Operation – Python Tutorial
6 years ago Lalit Bhagtani 0
Python has various types of string operators, which can be used to perform different operation on a given string like python string concatenation, string repetition etc.
In this tutorial, we will learn about the following:
- String Concatenation
- String Repetition
- String Contains
- String Not Contains
- String Length
Python String Concatenation
We can use addition ( + ) operator to concatenate ( join ) two strings together to create a new string.
# create first string and assign it to variable first
first = 'Hello '
# create second string and assign it to variable second
second = 'World'
# example of concatenation
concatenate = first + second
print(concatenate)
String Repetition
We can use multiplication ( * ) operator to concatenate ( join ) same string multiple times to create a new string.
# create first string and assign it to variable first
first = 'Hello '
# example of repetition
repetition = first * 3
print(repetition)
String Contains
We can use in operator to check, if a given substring is present in the string or not. If present then return True otherwise return False.
# create first string and assign it to variable first
first = 'Hello '
# example of contains
contains = 'He' in first
print(contains)
String Not Contains
We can use not in operator to check, if a given substring is present in the string or not. If present then return False otherwise return True.
# create first string and assign it to variable first
first = 'Hello '
# example of not contains
not_contain = 'He' not in first
print(not_contain)
String Length
We can use len() (Syntax: len(‘Your String’) ) function to get the length of a string. For example:
# create one string and assign it to variable s
s = 'Hello World'
# call len() method to get length of the string s and assign it to variable length
length = len(s)
# print the value of variable length
print(length)
