How to remove digits from the end of a string in Python 3.x?

You can use str.rstrip with digit characters you want to remove trailing characters of the string:

>>> 'asdfg123'.rstrip('0123456789')
'asdfg'

Alternatively, you can use string.digits instead of '0123456789':

>>> import string
>>> string.digits
'0123456789'
>>> 'asdfg123'.rstrip(string.digits)
'asdfg'

No, split would not work, because split only can work with a fixed string to split on.

You could use the str.rstrip() method:

import string

cleaned = yourstring.rstrip(string.digits)

This uses the string.digits constant as a convenient definition of what needs to be removed.

or you could use a regular expression to replace digits at the end with an empty string:

import re

cleaned = re.sub(r'\d+$', '', yourstring)
