(I do know C++ and Java, so I have some idea...). Specifically, my question is: how does a class method access class variables? They can't be totally unqualified (because that's very unpythonic). If they are qualified by the class's name, I see it as a very mild improvement on the current situation. You could suggest, for example, to qualify class variables by "class" (so you'd do things like: class.x = 1), but I'm not sure I like it. On the whole, I think it is a much bigger issue on how be denote class methods. Also, one slight problem with your method of denoting class methods: currently, it is possible to add instance method at run time to a class by something like class C: pass def foo(self): pass C.foo = foo In your suggestion, how do you view the possiblity of adding class methods to a class? (Note that "foo", above, is also perfectly usable as a plain function). I want to note that Edward suggested denotation by a seperate namespace: C.foo = foo # foo is an instance method C.__methods__.foo = foo # foo is a class method The biggest problem with that suggestion is that it doesn't address the common case of defining it textually inside the class definition. > I'd also like to ask (separately) that assignment to None be defined as a > no-op, so that programmers can write: > > year, month, None, None, None, None, weekday, None, None = gmtime(time()) > > instead of having to create throw-away variables to fill in slots in > tuples that they don't care about. Currently, I use "_" for that purpose, after I heard the idea from Fredrik Lundh. -- Moshe Zadka <mzadka@geocities.com>. http://www.oreilly.com/news/prescod_0300.html http://www.linux.org.il -- we put the penguin in .com
