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

When Python 2.7 comes out you can use its collections.Counter class

otherwise see counter receipe

Under Python 2.7a3

from collections import Counter
items = {"a": 600, "b": 75, "c": 75, "d": 90}    
c = Counter( items )

print(  dict( c.items() ) )

output is

{600: 1, 90: 1, 75: 2}
