  • old - the old substring to be replaced.
  • new is a replacement substring for the existing one.
  • count – (Optional) Indicates how many times users want to substitute the new substring for the old one.

Although strings cannot be changed, a function replaces characters on either a duplicate of the original string.

In order to avoid losing the new string, make sure to save it. Due to Python's immutability, once initialized, strings cannot be changed.

As a result, methods for editing lists cannot be applied to strings. Python, on the other hand, has a few functions for replacing characters in strings.
