What’s the equivalent of rsplit() with re.split()?

Question

rsplit() starts splitting at the end of the string. How can I start splitting at the end of the string when using re.split()?

Example:

import re
splitme = "a!b?c!d"
re.split(r"[!\?]", splitme, maxsplit = 1)

Returns:

a

But I want:

d

While I was writing this question, I realized I could use

re.split(r"[!\?]", splitme)[-1]

But that doesn’t seem like the most effective way since this splits the entire string, while we could stop after the first match (from the right).

Answer 1

There is no need to split if you just want the last one.

match = re.search(r'[^!?]*$', splitme)
if match:
    return match.group(0)
