Get key with maximum value in Dictionary in Python

A Python dictionary contains key value pairs. In this article we will see how to get the key of the element whose value is maximum in the given Python dictionary.

With max and get

We use the get function and the max function to get the key.

Example

dictA = {"Mon": 3, "Tue": 11, "Wed": 8}
print("Given Dictionary:\n",dictA)
# Using max and get
MaxKey = max(dictA, key=dictA.get)
print("The Key with max value:\n",MaxKey)

Output

Running the above code gives us the following result −

Given Dictionary:
{'Mon': 3, 'Tue': 11, 'Wed': 8}
The Key with max value:
Tue

With itemgetter and max

With itemgetter function we get the items of the dictionary and by indexing it to position one we get the values. Next we apply why the max function and finally we get the required key.

Example

import operator
dictA = {"Mon": 3, "Tue": 11, "Wed": 8}
print("Given Dictionary:\n",dictA)
# Using max and get
MaxKey = max(dictA.items(), key = operator.itemgetter(1))[0]
print("The Key with max value:\n",MaxKey)

Output

Running the above code gives us the following result −

Given Dictionary:
{'Mon': 3, 'Tue': 11, 'Wed': 8}
The Key with max value:
Tue
