How many items in a dictionary share the same value in Python

Question

Is there a way to see how many items in a dictionary share the same value in Python?

Let\'s say that I have a dictionary like:

{\"a\": 600, \"b\": 75         


        

Answer 1

>>> a = {"a": 600, "b": 75, "c": 75, "d": 90}
>>> b = {}
>>> for k,v in a.iteritems():
...     b[v] = b.get(v,0) + 1
...
>>> b
{600: 1, 90: 1, 75: 2}
>>>
