>>> d = {'a':0, 'b':1, 'c':2}
>>> t = d.items()
>>> t
dict_items([('c', 2), ('a', 0), ('b', 1)])

The result is a dict_items object, which is an iterator that iterates the key-value pairs. You can use it in a for loop like this:

>>> for key, value in d.items():
...     print(key, value)
...
c 2
a 0
b 1
