How to concatenate two strings in python?

A collection of one or more characters put in single, double or triple quotes is known as string. e.g.,- ‘Hello’, “Python”, “””Pythonpoint”””, etc.

Before we proceed, recall that strings are immutable. Thus, every time you perform something on string that changes it, python will internally create a new string rather than modifying the old string.

Here we’ll see how to concatenate two strings in python. There are different methods to do this.

• Using ‘+’ sign – We have used this operator as arithmetic operators before for addition. But when used with strings, + operator performs concatenation rather than addition.

e.g.,

a="Hello"
b=" World"
print(a+b)

e.g.,

• Using ‘*’ sign – We have used this operator as arithmetic operator before for multiplication. But when used with strings, * operator perform concatenation for the same string also known as replication.

e.g.,

a="5"
print(a*3)

• Using join() function- join() is used to concatenate two strings.

e.g.,

a="Hello"
b="World"
print(" ".join([a, b]))

This is all about concatenate two strings in python.
