The timeit module is commonly used via the convenience function timeit.timeit, which is listed in the documentation as the recommended "Python Interface":
http://docs.python.org/3/library/timeit.html

However, this function is not listed in __all__, meaning that it does not come up in IDLE when Ctrl-Space is pressed. It is also not mentioned in the module docstring, which says "Library usage: see the Timer class.".

Same applies to timeit.repeat(), save that it's not as commonly used. Both are listed in the online docs but not in the docstring or __all__.

I'm a new contributor so, not sure if I'm missing anything:

The issue seems straightforward to me, the exports should definitely be included in both - the docstring and __all__. Also, default_timer is documented and should be imported as well.

I've contributed a patch for the dev version. After a review, I can submit patches for all remaining versions.

Thanks!

As long as we are editing the module docstring, the last sentence should be deleted in 3.x patches, and the preceding sentence added to the preceding paragraph.

In 3.3+, the paragraph beginning "The difference in default timer function" is obsolete and should be removed.

Anuj, I believe patch is correct for 2.7, so I do not think more patch versions are needed now.

I see the __all__ change as both behavior fix and enhancement, so I don't know whether there should be one fix or four. I posted "Matching __all__ to doc: bugfix or enhancement?" on pydev to see what other think.

(Reminder to self: remove old code to handle absence of itertools from stdlib. This will break the current patch.)

New changeset dda8a6b8a351 by Terry Jan Reedy in branch 'default':
Issue #17414: Add timeit, repeat, and default_timer to timeit.__all__.
http://hg.python.org/cpython/rev/dda8a6b8a351

Fred Drake, Eli Bendersky, and in particular, Guido ("I do see that it shouldn't be backported, but I don't see any worries about doing it in 3.4.") said that this is a 3.4-only enhancement.

Anuj, ACKS are alphabetical. Åstrand is at the end because that is where Å sorts. Thanks for the patch. We hope to see more.
