Python math.pow() – Power of a Number

Python math.pow()

math.pow(x, y) function returns the value of x raised to the power y.

Syntax

The syntax to call pow() function is

math.pow(x, y)

where

ParameterRequiredDescription
xYesA numeric value.
yYesA numeric value.

If x and y are finite, x < 0, and y is not integer, then pow() raises ValueError.

Examples

In the following program, we find the 4 raised to the power of 3.

Python Program

import math

x = 4
y = 3
result = math.pow(x, y)
print('pow(x, y) :', result)
Run

Output

pow(x, y) : 64.0

x and y are finite, x < 0, and y is not an integer.

Python Program

import math

x = -1
y = 3.235
result = math.pow(x, y)
print('pow(x, y) :', result)
Run

Output

ValueError: math domain error

Infinity raised to the power of y.

Python Program

import math

x = math.inf
y = 3
result = math.pow(x, y)
print('pow(x, y) :', result)
Run

Output

pow(x, y) : inf

x raised to the power of infinity.

Python Program

import math

x = 3
y = math.inf
result = math.pow(x, y)
print('pow(x, y) :', result)
Run

Output

pow(x, y) : inf

x raised to the power of 0.

Python Program

import math

x = 3
y = 0
result = math.pow(x, y)
print('pow(x, y) :', result)
Run

Output

pow(x, y) : 1.0
