Category: Python Interpreter Core Group: None Status: Open Resolution: None Priority: 5 Submitted By: Ragnar Kj?rstad (ragnark) Assigned to: Nobody/Anonymous (nobody) Summary: Generator-support in map() and filter()

Initial Comment: The current implementation of map() and filter() returns a list when executed on any iterator, including generators.

However, it may be very useful to map and filter the output from generators without having to generate all the data and allocate memory for it.

I would propose for map() and filter() to return a generator-object instead of a list when the input-argument is a generator.
