Python create dictionary using dict with integer keys

Question

In Python  I see people creating dictionaries like this   d   dict  one   1  two   2  three   3     What if my keys are integers  When I try this   d   dict  1   1  2   2  3   3     I get an error  Of course I could do this   d     1 1  2 2  3 3     which works fine  but my main question is this  is there a way to set integer keys using the dict   function constructor

Yes  but not with that version of the constructor   You can do this    gt  gt  gt  dict   1  2    3  4     1  2  3  4    There are several different ways to make a dict   As documented   providing keyword arguments       only works for keys that are valid Python identifiers
