[Tutor] use gzip with large files

I am trying to write a script in python that parses a gzipped logfile
the unzipped logfiles can be very large (>2GB)
basically the statements
file = gzip.GzipFile(logfile)
data = file.read()
for line in data.striplines():
would do what I want, but this is not feasible becasue the gzip files
are so huge.
So I do file.readline() in a for loop, but have no idea how long to
continue, because I dont know how many lines the files contain. How do
I check for end of file when using readline() ?
simply put it in a while loop and enclose it with try: except: ?
what would be the best (fastest) approach to deal with such large gzip
files in python?
