I checked if file.read() is huge to some extend, it doesn't work, but
could any give me some certain information on this prolbem?
If the file's contents is larger than available memory, you'll get a
MemoryError. To avoid this, you can read the file in by chunks (or if
applicable, by lines) and see if each chunk/line matches.
If you're processing in chunks then you also need to consider the
possibility that what you're looking for crosses a chunk boundary, of
course. It's an easy case to miss! :-)
