[Python-Dev] Allowing slicing of iterators

Mon, 24 Jan 2005 03:30:08 -0800

I just wrote a new C API function (PyItem_GetItem) that supports slicing for arbitrary iterators. A patch for current CVS is at http://www.python.org/sf/1108272

For simple indices it does the iteration manually, and for extended slices it returns an itertools.islice object.

As a trivial example, here's how to skip the head of a zero-numbered list:

  for i, item in enumerate("ABCDEF")[1:]:
    print i, item


Is this idea a non-starter, or should I spend my holiday on Wednesday finishing it off and writing the documentation and tests for it?

Regards,
Nick.
