Also, it would be a nice place to point out for those coming from Java or

New submission from Chris Rebert :
The entry for "dictionary" reads in part:
[...] The keys can be any object with __hash__() function and __eq__()

__hash__() is a method, not a function (well, it's a "hash function" in the
computer science sense,

While converting code from Python 2 to Python 3, I came across the "gotcha"
that strings implement __iter__ in Python 3 but not in Python 2.
Looking through the documentation, I don't seem to see anything like this
mentioned in the lib
Chris Jerdonek added the comment:
It is not "so important." I just feel that the change should be acknowledged
somewhere -- insofar as the existing user documentation on iterator types
already discusses __iter__(). As it stands now, the Python 2 documentation is
a bit misleading
Chris Jerdonek added the comment:
Okay, then that also might be worth mentioning. As it stands now, the emphasis
in the section on iterator types is on __iter__() (e.g. it is the main focus of
the introduction), whereas iter() is barely mentioned (only in the sections on
