New submission from STINNER Victor: To speedup Python startup, I propose to reimplement the keyword module in C. Attached patch implements it.
* Remove Lib/keyword.py * Add Tools/scripts/keyword.py: script to build Modules/keyword.h * The new module is Modules/keyword.c I chose to change the keyword.kwlist type from list to tuple. The documentation only says they that kwlist is a "Sequence": http://docs.python.org/dev/library/keyword.html#keyword.kwlist The keyword is now used by the collections module in the implementation of namedtuple. The keyword module is trivial: it only contains a sequence of strings and a method checking if a string is part of this sequence. It would be simpler to add this to an existing module. I suppose that a new module was added for technical reasons. ---------- files: keyword.patch keywords: patch messages: 199528 nosy: christian.heimes, haypo, pitrou priority: normal severity: normal status: open title: Reimplement the keyword module in C type: performance versions: Python 3.4 Added file: http://bugs.python.org/file32054/keyword.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19230> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
