Is there an elegant way to strip all alphabetic characters from the end of a string?

Question

This works:

stripped_str = whatever_str.rstrip("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ")

but just seems very inelegant to me. Any cleaner way of doing it?

Answer 1

Perhaps you are looking for string.ascii_letters:

from string import ascii_letters
stripped_str = whatever_str.rstrip(ascii_letters)

It allows you to do the same as your current code, but without typing the entire alphabet.

Below is a demonstration:

>>> from string import ascii_letters
>>> ascii_letters
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
>>>
>>> '123abdjihdkffyifbgh'.rstrip(ascii_letters)
'123'
>>>
