How to implement it in my class?

The error is coming from the __new__ method. Because str is an
immutable type, you should override the __new__ method, not __init__.
or, if one is mere adding a method, do not add __new__ either.
Example:
class Str(str):
def __new__(cls, *args, **kwargs):
return super().__new__(cls, args[0])
Str('smth', kwarg='a')
'smth'
