Ive been having to dig into code vs documentation lately, and there
are *tons* of uses of items() vs iteritems(). I was wondering why this
is?
I did a quick benchmark, on an example I found in newforms, to try and
give myself an answer:
In [31]: timeit.Timer("attrs2=attrs.copy();[(field_name,
attrs2.pop(field_name)) for field_name, obj in attrs2.items()]",
"attrs = dict((('adfadsfasdf', 'hello'),)*10)").timeit()
Out[31]: 1.7580790519714355
In [32]: timeit.Timer("attrs2=attrs.copy();[(field_name, obj) for
field_name, obj in attrs2.iteritems()]", "attrs =
dict((('adfadsfasdf', 'hello'),)*10)").timeit()
Out[32]: 1.2866780757904053
The first example is what's currently in new forms, and I can't see it
saving much memory, for being that much slower.
