get highest value from dictionary python

ages = {'Matt' : 30, 'Katie': 29, 'Nik': 31, 'Jack': 43}

#get the max value in Python dict
max_value = max(ages.values())

find the highest 3 values in a dictionary.

from collections import Counter
# Initial Dictionary
my_dict = {'t': 3, 'u': 4, 't': 6, 'o': 5, 'r': 21}
k = Counter(my_dict)
# Finding 3 highest values
high = k.most_common(3)
print("Dictionary with 3 highest values:")
print("Keys: Values")
for i in high:
   print(i[0]," :",i[1]," ")

find the highest 3 values in a dictionary.

>>> sorted(my_dict, key=my_dict.get, reverse=True)[:3]
['K', 'B', 'A']
