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

You could use itertools.groupby for this.

import itertools
x = {"a": 600, "b": 75, "c": 75, "d": 90}
[(k, len(list(v))) for k, v in itertools.groupby(sorted(x.values()))]
