The documentation at http://docs.python.org/2/c-api/typeobj.html#PySequenceMethods is missing sq_slice between sq_item and sq_ass_item. This will mess up anyone trying to use anything after sq_item (that isn't using designated initializers).

Looking through Include/object.h I see that sq_slice is now:

void *was_sq_slice. Can anyone provide any clarification as to where I can find info about sq_slice?

If you look at the 2.7.3 version of that file: http://hg.python.org/cpython/file/70274d53c1dd/Include/object.h it has more information. It is a ssizessizeargfunc. I assume it passes the lower and upper bound and expects back a subsequence.

Just to clarify though, that is entirely an assumption as to how it's supposed to be used.

I was looking at 3.4 files. You're right it is in 2.7. Guess you have all the info you need to make a patch for it then?

ssizessizeargfunc PySequenceMethods.sq_slice

It passes the lower and upper bound and expects back a subsequence.

Or is there more to it than that? I cannot for the life of me make any sense out of it. Here I was sitting looking at this thinking it would be very easy doc fix for me but in the end I think I'll bow out.

I must admit I'm a little new to the development side of things. Can someone point me at a repo or something that the documentation files are in? I'm sort of guessing that the html is the processed output of something.

See http://docs.python.org/devguide/ and the Doc/c-api dir in the CPython repo.

Python 2.7 is no longer supported.
