naming conventions

I guess there are some personal presence here,and also that only one of exciting string methods use snake_case.
I personally in this case would have probably gone for this.

remove_suffix
remove_prefix

The one is.

>>> s = 'hello'
>>> s.format_map
<built-in method format_map of str object at 0x000002C7C5C0E3F0>

The rest without special method's __something__.

>>> dir(s)[33:]
