  3. To create a stream object out of a string, create an instance of the io.StringIO() class and pass it the string you want to use as your “file” data. Now you have a stream object, and you can do all sorts of stream-like things with it.

Handling Compressed Files

The Python standard library contains modules that support reading and writing compressed files. There are a number of different compression schemes; the two most popular on non-Windows systems are gzip and bzip2. (You may have also encountered PKZIP archives and GNU Tar archives. Python has modules for those, too.)
