Is there a common interface in Python that I could derive from to modify behavior of a generator?
For example, I want to modify an existing generator to insert some values in the stream and remove some other values.
How do I do that?
Thanks, Boda Cydo
You can use the functions provided by itertools to take a generator and produce a new generator.
For example, you can use takewhile until a predicate is no longer fulfilled, and chain on a new series of values.
Take a look at the documentation for other examples, including things like ifilter, dropwhile and islice to name just a few more.
