Here, we will see how to insert to a string python.

• To insert into a string we will use indexing in python.
• Inserting into a string returns the string with another string inserted into it at a given index.
• In this example, we are inserting “New York” into “Los Angeles, Chicago” and it returns “Los Angeles, New York, Chicago”.

Example:

str1 = "Los Angeles, Chicago"
str2 = "New York, "

N = 1
res = t_str.rjust(N + len(t_str), '0')
print("The string after adding zeros : " + str(res))

• To insert a character we will use slicing a_str[:1] + “n” + a_str[1:] and the “+” operator is used to insert the desired character.

Example:

a_str = "Hello"
a_str = a_str[:1] + "n" + a_str[1:]
