How to Use Key Function in Max() and Min() in Python code example

Example 1: python find the key with max value

a_dictionary = {"a": 1, "b": 2, "c": 3}

# get key with max value
max_key = max(a_dictionary, key=a_dictionary.get)

print(max_key)

Example 2: python get the key with the max or min value in a dictionary

# Basic syntax:
key_with_max_value = max(dictionary, key=dictionary.get)

# Note, to get the max value itself, you can do either of the following:
max_value = dictionary[max(dictionary, key=dictionary.get)]
max_value = max(dictionary.values())

# Example usage:
dictionary = {"a": 1, "b": 2, "c": 3}
max(dictionary, key=dictionary.get)
--> 'c'
