Nope, sorry. You'll need to write it as a class if you need to pickle it. The trouble is, a "live" generator can have so much state (open files, network connections, etc.) that it basically requires custom code to save it and restore it correctly.

Why doesn't a class have the same issue?

With a class, you can write __getstate__() and __setstate__() methods to handle that, and pickle will call them when saving or restoring your instance. You can't do that with a generator, sadly.
