And I guess this is subjective: conversely, the API you're proposing doesn't feel Pythonic to me. :-) I'd like the hear the opinion of other python-dev readers.
I agree with Mark: the proposed median, median.low, etc., doesn't feel right. Is there any example of doing this in the stdlib? I suggest just median(), median_low(), etc.
I too prefer the median_low naming rather than median.low. I'm not sure I can articulate why, but certainly the fact that that latter isn't used anywhere else in the stdlib that I can think of is probably a lot of it :)
Perhaps the underlying thought is that we don't use classes pure function namespaces: we expect classes to be something more than that.
Certainly. Python does not force the "everything is a class" philosophy of Java and Ruby. Classes have their uses, but namespacing isn't it. There are modules for namespaces. Eli
