Changing one character in a string

Question

What is the easiest way in Python to replace a character in a string?

For example:

text = \"abcdefg\";
text[1] = \"Z\";
           ^

Answer 1

Strings are immutable in Python, which means you cannot change the existing string. But if you want to change any character in it, you could create a new string out it as follows,

def replace(s, position, character):
    return s[:position] + character + s[position+1:]

replace('King', 1, 'o')
// result: Kong

Note: If you give the position value greater than the length of the string, it will append the character at the end.

replace('Dog', 10, 's')
// result: Dogs
