[solved] Regex expression do not want to taken :/

[SpongeB0B]

Hi everyone,

I've already used the module re a couple of times. but this time I have one expression that I can't pass to Python without getting an error

The expression

(?<=^([^"']|["'][^"']*["'])*)#.*

sample string to test expression upon

#this is a test
#this is another test
x = None #another test

"This is a string with # Hash symbol" #a comment right after.

on regexr.com this combo work.

but when I try in my code

x = re.compile( r'(?<=^([^"\']|["\'][^"\']*["\'])*)#.*' )

I got

Error:
re.error: look-behind requires fixed-width pattern

Any ideas ?

Thanks
