re.MULTILINE
	When specified [...] the pattern character "$" matches at the
	end of the string and at the end of each line (immediately
	preceding each newline). By default [...] "$" matches only at
	the end of the string.

re.DOTALL
	[...] without this flag, "." will match anything except a newline.

So a simple solution to your problem would be:

r = re.compile("//.*")
f_new = r.sub("", f)
