values() returns (surprise!) just the values of the dict.  I think you meant
items() which returns both the keys and the values:

for key, value in my_dict.items():
    print key, value

I think what the person below was after is the common python idiom:

for k in my_dict.keys():
    print my_dict[k]
    my_dict[k] = my_dict[k] + 1
    # etc.
