Regex for a particular character in an unpaired tag

I’m trying to find a character within an unbalanced pair of tags. I can identify it within a matched set, and when the matching pairs are a single character each, but I can’t seem to hit on the syntax to find it within an unmatched set when the pairs are multiple characters each. I’ve tried several combinations of lookaheads without success.

why is using regex group feature on Python giving different Outputs

import re string1 = “aaabaa” zusuchen = “aa” #1 m_start = re.finditer(fr'(?=({zusuchen}))’, string1) results = [(match.start(1), match.end(1)-1) for match in m_start] for z in results: print(z) print(“Now #2:”) #2 m_start = re.finditer(fr'(?={zusuchen})’, string1) results = [(match.start(), match.end()-1) for match in m_start] for z in results: print(z) I still haven’t figured out what’s the problem for […]

Why Is my Regex Is Unable to Find Sentences at the End of Text?

I am using python to parse emails to feed into an LLM and I need to truncate these emails if the text is too long. I am using TikToken to check length and I want to strip out text one sentence at a time – with a sentence starting with anything but always ending with a period, exclamation point, question mark or new line return (nr).
