如何在数字出现正则表达式之前获取字符串的最后一部分？

Question

I'm using Python 3.8 to loop through each string in a list. I want to extract only the colors at the end.

As it seems that the colors are divided from the model's names by a date (or at least a word with some digits in it), I'm trying to use the python librairy 're' to split the strings. But I can't figure out how to start from the end rather than the beginning?

Jackson_Phil_Demmel_Demmelition_King_V_2010s_Standard_Finish
Paul_Reed_Smith_513_2012_Black_Slate
Paul_Reed_Smith_408_TM_with_Artist_Package_2013_Whale_Blue
Paul_Reed_Smith_408_MT_2013_Livingston_Lemondrop
Paul_Reed_Smith_20th_Anniversary_12-string_with_10-top_2005_Yellow_Burst
Paul_Reed_Smith_Brent_Mason_Signature_2Epiphone_EA-255_Casino_1970s_Walnut
Epiphone_Limited_Edition_Wilshire_Pro_2000s
Epiphone_Coronet_1966_Cherry010s_Transparent_Finish
Epiphone_Matt_Heafy_Signature_7-String_Les_Paul_Custom
B.C._Rich_Mockingbird_late_80s_Black_Sparkle
GandL_ASAT_Classic_1990s_Solid_Finish_or_Sunburst

how do I split those strings to only keep the end result?

Answer 1

Something like '.*[0-9]s?_(.*)' should work, then take the group.

eg:

import re

for s in [
    'Jackson_Phil_Demmel_Demmelition_King_V_2010s_Standard_Finish',
    'Paul_Reed_Smith_513_2012_Black_Slate',
    'Paul_Reed_Smith_408_TM_with_Artist_Package_2013_Whale_Blue',
    'Paul_Reed_Smith_408_MT_2013_Livingston_Lemondrop',
    'Paul_Reed_Smith_20th_Anniversary_12-string_with_10-top_2005_Yellow_Burst'
    'Paul_Reed_Smith_Brent_Mason_Signature_2Epiphone_EA-255_Casino_1970s_Walnut',
    'Epiphone_Limited_Edition_Wilshire_Pro_2000s',
    'Epiphone_Coronet_1966_Cherry010s_Transparent_Finish',
    'Epiphone_Matt_Heafy_Signature_7-String_Les_Paul_Custom',
    'B.C._Rich_Mockingbird_late_80s_Black_Sparkle',
    'GandL_ASAT_Classic_1990s_Solid_Finish_or_Sunburst']:

    m = re.match('.*[0-9]s?_(.*)',s)
    color = m.groups()[0] if m else 'NONE'

    print(f'{s}:\t{color}')
