'as_dict' is an unlikely fieldname. 're_place' is too, but that just shift the '_' from '_replace'. No gain. I might prefer _asdict to _as_dict, but not enough to change. Probably a stupid idea (sorry) but one could just make asdict() and replace() public methods with the caveat that developers not use those as field names. cheers James -- -- James Mills -- -- Problems are solved by method ___ 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

[I mentioned this to Raymond Hettinger after his PyCon talk, and I

Because named tuple prefixes a single underscore to its added method
names (_asdict, _replace, and _make), those methods' docstrings are
omitted from pydoc:
Point=collections.namedtuple('Point', 'x y')
help(Point)
Help on class Point in module __main__:
[output omitted; it excludes _asdict, _replace, and _make]
pydoc's rules for name inclusion are in pydoc.visiblename():
* If the name is in the hidden list, omit it
* If the name looks like a __special_method__, include it
* If the there is an all specified, then include it if it appears in all
* Otherwise, include it if it doesn't begin with an underscore
There doesn't seem to be an obvious way to get around these rules for
named tuples... am I overlooking something?
Works for me. Python 3.2 on 32bit Linux.

I may try working on it some more, since there seems to be some interest. So far in this discussion (I'm not really contributing very much) I agree with several things: a) We should have a PEP outlining the proposed new async lib. b) It should be general purpose enough to use without Twisted (for example) I like the idea of having an async core in the std. lib that takes care of cross-platform polling of I/O descriptors, notifications and timers. cheers James -- -- James Mills -- -- Problems are solved by method ___ 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

[Python-Dev] multiprocessing vs. distributed processing
I've noticed over the past few weeks lots of questions asked about multi-processing (including myself). For those of you new to multi-processing, perhaps this thread may help you. Some things I want to start off with to point out are: multiprocessing will not always help you get things done faster. be aware of I/O bound applications vs. CPU bound multiple CPUs (cores) can compute multiple concurrent expressions - not read 2 files concurrently in some cases, you may be after distributed processing rather than multi or parallel processing cheers James -- -- Problems are solved by method ___ 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
