rsplit() starts splitting at the end of the string. How can I start splitting at the end of the string when using re.split()?
rsplit（）在字符串的末尾开始拆分。使用re.split（）时，如何在字符串末尾开始拆分？
Example:
例：
import re
splitme = "a!b?c!d"
re.split(r"[!\?]", splitme, maxsplit = 1)
Returns:
返回：
a
But I want:
但我想要：
d
While I was writing this question, I realized I could use
当我写这个问题时，我意识到我可以使用
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).
但这似乎不是最有效的方法，因为这会拆分整个字符串，而我们可以在第一场比赛后（从右边）停止。

There is no need to split if you just want the last one.
如果您只想要最后一个，则无需拆分。
match = re.search(r'[^!?]*$', splitme)
if match:
return match.group(0)
