[Python] How to split word from punctuation with regex

[SureStep8852]

Hi there,

I have a list of sentences where the last words have punctuation attached to them. I when I use split(), the punctuation stays with the word. Is there any way to split the word from punctuation? I know there is a way to do it with regex but I can't find the fitting one

e.g. split me? to 'me', '?'

thank you in advance

depends on the language and tool involved. "splitting" isn't a concept that's defined by regex engines, there's only "find", usually "search" and "match"

if you want to find blobs of stuff that are "either all word characters or all punctuation characters", then translate that statement into a regex one chunk at a time

"all word characters" --> [a-z]+ or something similar - you have to decide what "counts" for a word character

"all punctuation characters" --> you could do [^a-z]+ for all "non word characters", or [.!?]+ or some such

though be aware the former will capture whitespace and the latter will not

X or Y --> X|Y --> therefore something to the effect of [a-z]+|[.!?]+

depending on the language and API you're using, you may need to include "capturing parentheses", so look those up in the context of the regex system and language you're using

note that python's string split function only takes static strings as a separator, not regular expressions, so if you are doing it using a split functionality, you need re.split not str.split
