max value in dictionary 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'

Example 3: max of a dict

dic={0: 1.4984074067880424, 1: 1.0984074067880423, 2: 1.8984074067880425, 3: 2.2984074067880425, 4: 2.2984074067880425}
max_value = max(dic.values())  # maximum value
max_keys = [k for k, v in dic.items() if v == max_value] # getting all keys containing the `maximum`

print(max_value, max_keys)

Example 4: find the max value in dictionary python

my_dict = {'a': 5, 'b': 10, 'c': 6, 'd': 12, 'e': 7}
max(my_dict, key=my_dict.get) # returns 'd'

Example 5: max element in dictionary python

import operator
stats = {'a':1000, 'b':3000, 'c': 100}
max(stats.iteritems(), key=operator.itemgetter(1))[0]

Example 6: get max n values in dict py

import heapq
from operator import itemgetter

n = 3

items = {'a': 7, 'b': 12, 'c': 9, 'd': 0, 'e': 24, 'f': 10, 'g': 24}

topitems = heapq.nlargest(n, items.items(), key=itemgetter(1))  # Use .iteritems() on Py2
topitemsasdict = dict(topitems)
