Zitat von Chris Withers <ch...@simplistix.co.uk>:
a_dict = dict( x = 1, y = 2, z = 3, ... )
What can we do to speed up the former case?
It should be possible to special-case it. Rather than creating a new dictionary from scratch, one could try to have the new dictionary the same size as the original one, and copy all entries. I also wonder whether the PyArg_ValidateKeywordArguments call is really necessary: if this is not a proper keyword dictionary, dict creation could still proceed in a reasonable way. I don't know how much this would gain, though. You still have to create two dictionary objects. For a better speedup, try def xdict(**kwds): return kwds (possibly written in C for even more speed) Regards, Martin _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
