Guido, creator of Python talks about what is going to be included in Python 3000. For instance, right now in Python 2.4 if you have a list such as:
>>> a_list = [2, 1, ""]
>>> a_list.sort()You get back a sorted list:
[1, 2, '']
In Python 3000 you should get a TypeError.
One of the many items that might be useful to Python programmers coding future proof code, is covered by this talk.
