Get the key corresponding to the minimum value within a dictionary

Question

If I have a Python dictionary, how do I get the key to the entry which contains the minimum value?

I was thinking about something to do with the min() function...

Given the input:

{320:1, 321:0, 322:3}

It would return 321.

Answer 1

The best way to get the key corresponding to the minimum value within a dictionary is to use the following way:-

d = {320:1, 321:0, 322:3}

min(d, key=d.get) 

There is no reason to interpose a useless lambda indirection layer or extract items or keys.
