how to find the maximum value of a dictionary in python code example

Example 1: 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 2: python get min max value from a dictionary

d = {'A': 4,'B':10}
min_v = min(zip(d.values(), d.keys()))
# min_v is (4,'A')

max_v = max(zip(d.values(), d.keys()))
# max_v is (10,'B')

Example 3: max element in dictionary python

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

Example 4: 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)
