Well, what does the python interpreter say?

sorry i forgot ,and i just updated the post

Please can you post the exact code that you're running with the exact error message. It is meaningless to use the error message of another piece of code.

it's done and sorry
RE: regular expression and sub - Gribouillis - Nov-03-2019
re.sub() needs a second argument saying by what you want to replace the match in the initial string. Here you can use
case = re.sub(match, '', expression)or
match.sub('', expression)Also 'match' is not a very good name for a regex because it's often used for match objects which appear in this context. Better use 'pattern' or 'regex' or 'pat'...

thank you, i thought that's took just 2 argument.
and i will change the match object.
