looping a unnamed dictionary in python

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

You can use the iteritems method to iterate through the dict

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

To iterate over key/value pairs, you can use .items() or .iteritems():

for k, v in {'one':1, 'two':2, 'three':3}.iteritems():
    print '%s:%s' % (k, v)

See http://docs.python.org/library/stdtypes.html#dict.iteritems

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).

Sure, just use:

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

You could do:

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