Question

This gives the max value in a dict, but how do I get the dict key for the max value?

max([d[i] for i in d])

Answer 1

Use the key= keyword argument to max():

max(d, key=lambda k: d[k])

Instead of the lambda you can use operators.itemgetter as well:

import operators
max(d, key=operators.itemgetter(d))

or pass in d.get:

max(d, key=d.get)
