Python删除字符串的最后一个字符，如果它是一个字母

Question

How do I remove the last character of a string if its a letter.

eg if I had the following strings.

my_string = 'ABC 1.1 A'
my_string2 = 'ABC 1.1 B'
my_string3 = 'DEF 1'

I would want my_string = 'ABC 1.1' , my_string2 = 'ABC 1.1' , and my_strin3 = 'DEF 1'

These strings are generated from DB so it would not be a manual process.

Answer 1

You can use str.rstrip() :

import string
my_string = my_string.rstrip(string.ascii_letters + string.whitespace)

This will remove all letters and whitespace characters from the end of the string.

Answer 2

try this:

import string
if my_string[-1] in string.ascii_letters:
    my_string = my_string[0:-1].strip()
