replace

Learn text replacement with replace.

replace replaces substrings in a string with another substring:

"hello world".replace("world", "Python")
# "hello Python"

By default it replaces all matches. A maximum count can be given as a third parameter:

"a-b-c".replace("-", "+", 1)
# "a+b-c"

replace also returns a new string; it does not modify the original.

Limiting replace count

The third parameter limits how many replacements happen:

"a-b-c-d".replace("-", "+", 2)
# "a+b+c-d"

This is useful when you only want the first N changes. For example, to change the first separator in a file path.

If no third parameter is given, all matches are replaced.

Assign "hello world" to text. Assign text.replace("world", "Python") to result. Then print print(result).
