looping a unnamed dictionary in python

Question

Is there a way to print both key and value of a anonymous dict in python.

for key in {'one':1, 'two':2, 'three':3}:
    print key, ":", #value

Answer 1

for key, value in {'one':1, 'two':2, 'three':3}.iteritems():
    print key, ":", value

By default, iterating over it returns its keys. .iteritems() returns 2-tuples of (key, value).

Answer 2

You could do:

for  (key, value) in {'one':1, 'two':2, 'three':3}.items():
    print key, value
