What method(s) does a class have to support to properly emulate a container which supports turning it into a list? For example:class Foo: pass f = Foo() print list(f) Is it just __iter__() and next()? (I'm still using 2.4 and 2.7.)
You can either use __iter__ and next to conform to the iterator protocol, or you can define __getitem__. If using __getitem__ it needs to work with integers from 0 to len(f)-1, and raise IndexError for len(f), len(f+1), etc. ~Ethan~ -- http://mail.python.org/mailman/listinfo/python-list
