Python Math Functions and Math Module

Python provides several built-in mathematical functions for basic calculations. For advanced mathematical operations, Python also includes a powerful math module.

Built-in Math Functions

Finding Minimum and Maximum Values

The min() and max() functions help you quickly determine the smallest and largest values from a collection of numbers.

Example: Find the minimum and maximum values from a set of numbers.

numbers = [12, 45, 7, 89, 23] lowest = min(numbers) highest = max(numbers) print("Minimum value:", lowest) print("Maximum value:", highest)

Output:

Minimum value: 7
Maximum value: 89

Absolute Value

The abs() function converts a negative number into its positive form, while positive numbers remain unchanged.

Example: Get the absolute value of a number.

value = -15.8 result = abs(value) print("Absolute value:", result)

Output:

Absolute value: 15.8

Power Function

The pow() function raises a number to a specified power.

Example: Calculate 3 raised to the power of 4.

result = pow(3, 4) print("Power result:", result)

Output:

Power result: 81

Python Math Module

For more complex mathematical calculations, Python provides the math module. To access its features, you must import it first.

Syntax: import math

Square Root Calculation

The math.sqrt() function returns the square root of a number.

import math number = 81 root = math.sqrt(number) print("Square root:", root)

Output:

Square root: 9.0

Rounding Numbers

    • math.ceil() rounds a number up to the nearest integer.

    • math.floor() rounds a number down to the nearest integer.

import math value = 6.7 rounded_up = math.ceil(value) rounded_down = math.floor(value) print("Ceil value:", rounded_up) print("Floor value:", rounded_down)

Output:

Ceil value: 7
Floor value: 6

Mathematical Constant π (Pi)

The math.pi constant provides an accurate value of π (pi), commonly used in geometry and trigonometry.

import math radius = 5 area = math.pi * radius * radius print("Area of circle:", area)

Output:

Area of circle: 78.53981633974483
