The max() And min() Functions In Python

Python has many pre-defined functions, including the max() and min() functions . Here's what they are-

The max() Function

This function is quite easy to understand. Like the name suggests, it takes a given sequence (list, tuple, dictionary, set, etc) and, in case of a number, gives the highest value as the output and in case of strings, gives the element that is alphabetically last in the sequence.

Let's look at an example to understand it better-

seq=("Hello", "Bye", "Donald", "Duck")

print(max(seq1))

The output-

Hello

Note: Uppercase characters are considered to be before lowercase ones. So, if you have 2 elements in a sequence, 1 beginning with an uppercase character and the other with a lowercase one, the max() function will give the element beginning with a lowercase character as the output

Here's an example of such a situation-

seq=("Zinc", "aluminium")

print(max(seq))

The output-

aluminium

If you include mixed data types in the sequence (like string and integer), you will get an error as this function can only be used with similar data types.

For example-

seq=("Hello", 123)

print(max(seq))

The output-

Traceback (most recent call last):
  File "/Users/'username'/'folder'/'filename'", line 3, in <module>
    print(max(seq))
          ^^^^^^^^
TypeError: '>' not supported between instances of 'int' and 'str'

To end this topic, here's an example of the function being executed on a sequence having numbers-

seq=(450, 30, 96, 120.3, 756)

print(max(seq))

The output-

756

The min() Function

The min() function is the exact opposite of the max() function. It takes a given sequence, and gives the smallest element as output. In case of strings, it takes the word beginning with the earliest letter as per the alphabet as the smallest value.

An example with string values-

seq=("Hello", "Bye", "Donald", "Duck")

print(min(seq))

The output-

Bye

An example with numbers-

seq=(1, 784, 943, 102)

print(min(seq))

The output-

1

Just like the max() function, you get an error if you mix string data types with numerical data types like float and int.
