Answer 1

When you use [.*] it does a greedy match, so everything from [a till b] is matched and substituted for the empty string ''.

When you use [.?], it matches anychar . zero or 1 time ? which are inside []. And so [a] and [b] are matched.

import re

with open('file1.txt') as file1:
    file1 = file1.read()
test = re.sub(r'[([].?[)]]', '', file1)

print(test)
