Is there a good shortcut for modifying python variables using methods?

Question

i += 1 can be used instead of i = i + 1.

Is there a similar shorthand for string = string.replace(...)?

Answer 1

The type string supports the += operator. You can write str += "hello" but such shortening does not work for functions. The type string is immutable

A function like string.replace returns a new string and therefore you have to replace it against your old string (if that's what you want).
