Another approach is to subclass dict such that each time you add a
key:value pair you also create an entry in a reverse dictionary. Then
all you need do is lookup in the reverse dictionary.
If there are several keys with the same value, then create and extend a
list of values in the reverse di

Note that if there are multiple keys with the same value, my function
would get only the first. It wouldn't be hard to modify the function to

What if i have to print reverse???
A dictionary can be viewed
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.i
