Regular expressions

Question

import re
def solution(s, markers):
markers = "".join(markers)
return re.sub(r'\s(?=\n)', '', re.sub(rf'[{markers}][^\n]+', '', s)).rstrip()
print(solution("\n#", ["#", "!"]))
this code removes everything between the markers and a new line, but when the input is "\n#" it does not work. This is my first time using regular expressions so iam completely clueless on what to do, please help.
