If you pass a dictionary to the max() function, then it returns the key with the maximum worth. The syntax of the method is as follows:

max(dict)

See the following example:

>>> dict1 = {1:"abc",5:"hj", 43:"Dhoni", ("a","b"):"game", "hj":56}
>>> max(dict1)
('a', 'b')

So, the max function gives the tuple the maximum worth. Similarly, to get the minimum key, you can use the min() function.
