Python Math
Python has a set of built-in math functions, including an extensive math module, that allows you to perform mathematical tasks on numbers.
Built-in Math Functions
The min() and max() functions can be used to find the lowest or highest value in an iterable:
The abs() function returns the absolute (positive) value of the specified number:
The pow(x, y) function returns the value of x to the power of y (xy).
Example
Return the value of 4 to the power of 3 (same as 4 * 4 * 4):
x = pow(4, 3)
print(x)

The Math Module
Python has also a built-in module called math, which extends the list of mathematical functions.
To use it, you must import the math module:
import math
When you have imported the math module, you
can start using methods and constants of the module.
The math.sqrt() method for example, returns the square root of a number:
The math.ceil() method rounds a number upwards to
its nearest integer, and the math.floor()
method rounds a number downwards to its nearest integer, and returns the result:
Example
import
math
x = math.ceil(1.4)
y = math.floor(1.4)
print(x) #
returns 2
print(y) # returns 1

The math.pi constant, returns the value of
PI (3.14...):
