The distinction you're making is push vs. pull processing.  To get what
you want, you should use some sort of asynchronous mechanism with
synchronization when data is transferred.  Threading with the use of the
Queue module comes to mind immediately.  Other forms of asynchronous
processing are certainly possible, as well.

That being said, calling the next method of a generator _is_ the obvious
inverse process of a generator yielding a value.
