Python Ranking Dictionary Return Rank

Question

I have a python dictionary:

x = {\'a\':10.1,\'b\':2,\'c\':5}

How do I go about ranking and returning the rank value? Like getting back:

Answer 1

You could do like this,

>>> x = {'a':10.1,'b':2,'c':5}
>>> m = {}
>>> k = 0
>>> for i in dict(sorted(x.items(), key=lambda k: k[1], reverse=True)):
        k += 1
        m[i] = k


>>> m
{'a': 1, 'c': 2, 'b': 3}
