regex to remove characters between semicolon and period mark

how can I write a regex to remove the words coming after semicolon until it gets to the first period mark?

for instance:

try to be nice; underastand people. start fresh.

I want to remove "understand people" and have something like

try to be nice. start fresh

this is my regex but sadly it does not work:

sentence = ''.join(re.sub(r';.*?.', '.', sentence))

Thanks!

You forgot to escape the dot: r';.*?\.'. Also, there is no need to join anything here, you pass a string to re.sub and you get a string after.

A r';[^.]+' regex seems better though as it will match a ; and 1+ chars other than a literal dot (so, you can replace with an empty string):

import re
sentence = "try to be nice; underastand people. start fresh."
sentence = re.sub(r';[^.]+', '', sentence)
print(sentence)
# => try to be nice. start fresh.
