Python Math Module (Math)

Understand all the mathematical functions available in Python and how to use them in programs.

What is the mathematical module in Python?

math Moduleis a standard module in Python and is always available. To use mathematical functions under this module, you must use the import module import math.

It provides access to basic C library functions. For example,

Example

#　Square root calculation
import　math
math.sqrt(4)

This module does not support complex data types.CMATH moduleare complex correspondences.
