45

More Python min() Examples

In this example, we find the minimum element in different reference using Python min().

Example 1: Find Python Min of List

In this example, we are using min() to locate the smallest item in Python in a list.

Python

numbers = [3, 2, 8, 5, 10, 6]
small = min(numbers);
 
print("The smallest number is:", small)

                    

Output
The smallest number is: 2



Example 2: Find min in List of String

In this example, we are using min() to locate the smallest string in Python in a list.

Python

languages = ["Python", "C Programming", "Java", "JavaScript",'PHP','Kotlin']
small = min(languages)
print("The smallest string is:", small)

                    

Output

The smallest string is: C Programming

Example 3: Minimum Element in a Dictionary

In this example, we are using min() to find the minimum element in a dictionary.

Python

square = {5: 25, 8: 64, 2: 4, 3: 9, -1: 1, -2: 4}
 
print("The smallest key:", min(square))    # -2
 
key2 = min(square, key = lambda k: square[k])
 
print("The smallest value:", square[key2])    # 1

                    

Output
The smallest key: -2
The smallest value: 1



In this article, we discussed the definition, syntax, and examples of the Python min() function. min() function in Python is very versatile and can be used with any iterable.
