Is collections.KeysView good for you? On Tue, Feb 12, 2013 at 9:05 AM, Chris Withers <chris@simplistix.co.uk> wrote:
Hi all,
So, dicts in Python 3 return "something different" from their keys and values methods:
dict(x=1, y=2).keys() dict_keys(['y', 'x']) type(dict(x=1, y=2).keys()) <class 'dict_keys'>
I have vague memories of these things being referred to as views or some such? Where can I learn more?
More importantly, how can I tell if I have one of them? I guess I can keep a reference to type({}.keys()) somewhere, but that feels a bit yucky. Should these things be in the types module?
cheers,
Chris
