Basic operators–

The two basic operators of strings are: ‘+’ and ‘*’.
We have used these operators as arithmetic operators for addition and multiplication respectively. But when used with strings, ‘+’ operator performs concatenation rather than addition and ‘*’ operator performs replication rather than multiplication.

Concatenation– Concatenation means that ‘+’ sign joins two strings and prints it.

e.g.,

s='python'
a='point'
print(s+a)

Output- pythonpoint

Replication– To use ‘*’ operator with strings, we need two type of operands- a string and a number. The string operand tells the string to be replicated and the number operand tells the number of times it is to be repeated.

e.g.,

s=" Hi"
a=3
print(s*a)

Output- Hi Hi Hi

Membership operators-

There are two membership operators for string:- in and not in.

in- Returns True if a character or a string exists in the given string, false otherwise.

e.g.,

s="pythonpoint"
print("n" in s)

Output- True

not in- Returns True if a character or a string does not exist in the given string, false otherwise.

e.g.,

s="pythonpoint"
print("z" not in s)

Output- True

This is all about basic operations on string in python.
