Like everyone else here, I recommend using the string find() method instead,
for this specific case.
More generally, if you *need* a regexp, there's a trivial solution: don't
screw with the regexp, invert the result of the *test*:
searcher = re.compile("skip").search
while 1:
...
if searcher(line):
# found it
else:
# no "skip" in this line!
A funkier way is to fool around with negative lookahead assertions, like
searcher = re.compile("(?!.*skip)", re.DOTALL).match
This fails to match if it can find "skip", and matches an empty string at the
start if it can't find "skip".
