Key of Min Value

Introduction

In Python, dictionaries are a useful data structure for storing key-value pairs. Sometimes, we may need to find the key of the minimum value in a dictionary. In this challenge, you will be tasked with writing a function that finds the key of the minimum value in a given dictionary.

Key of Min Value

Write a function key_of_min(d) that takes in a dictionary d as its argument and returns the key of the minimum value in the dictionary.

To solve this problem, you can use the built-in min() function with the key parameter set to dict.get(). This will return the key of the minimum value in the dictionary.

def key_of_min(d):
  return min(d, key = d.get)

key_of_min({'a':4, 'b':0, 'c':13}) ## b

Summary

In this challenge, you learned how to find the key of the minimum value in a dictionary using Python. By using the min() function with the key parameter set to dict.get(), you can easily find the key of the minimum value in a given dictionary.
