The PEPs & post-release docs detailing Py3 changes were worth reading, it's noted in the sections on changes to built-ins: http://www.python.org/dev/peps/pep-3100/ http://docs.python.org/py3k/whatsnew/3.0.html > A) how is Callable a collection, in any way shape or form? And B) does > that really return True for everything callable-esque? (I don't have a > 3.x to play with on this temporary computer) A) I was tempted to say "it's a collection of code" :) But really, the role of the collections model has expanded in 3.x to also provide a repository for ABCs: "In addition to containers, the collections module provides some ABCs (abstract base classes) that can be used to test whether a class provides a particular interface, for example, whether it is hashable or a mapping." http://docs.python.org/py3k/library/collections.html B) In a quick test in 3.1.2, it returned true for a function, a bound and unbound lambda, and an instance of a class with a __call__ defined. If there's any other kind of callable you can think of, let me know and I'll be happy to test it. -- http://mail.python.org/mailman/listinfo/python-list
