it would work like this sub("pattern","replace", txt, flags= re.IGNORECASE | re.DOTALL)
but it wouldnt work like this  sub("pattern","replace", txt, re.IGNORECASE | re.DOTALL)

The arguments are: re.sub(pattern, repl, string, count=0, flags=0).

Therefore:

    re.sub("pattern","replace", txt, re.IGNORECASE | re.DOTALL)

is passing re.IGNORECASE | re.DOTALL as the count, not the flags.

It's in the documentation and the interactive help.
