Hi,
Keys are unique in a dictionaire but values aren't. What do you want to
print if you have the next dictionaire:
dict = {'a' : 1, 'b' : 1}
If you are using python 2.7 you can use dictionary comprehensions to swap
keys for values:
>>> d={'a':1,'b':2,'c':3}
>>> new_dict = {v : k for k,v in d.iteritems()}
>>> new_dict
{1: 'a', 2: 'b', 3: 'c'}
but if you're values are repeated you will loose some keys:
>>> dict = {'a' : 1, 'b':1}
>>> {v : k for k,v in dict.iteritems()}
{1: 'b'}
HTH,
Raúl
