Python Number pow() Method


Advertisements

Description

Python number method pow() returns x to the power of y. If the third argument (z) is given, it returns x to the power of y modulus z, i.e. pow(x, y) % z.

Syntax

Following is the syntax for pow() method −

import math

math.pow( x, y[, z] )

Note − This function is not accessible directly, so we need to import math module and then we need to call this function using math static object.

Parameters

  • x − number which is to be powered.

  • y − number which is to be powered with x

  • z − (Optional) number which is to be used for modulus operation

Return Value

This method returns value of xy.

Example

The following example shows the usage of pow() method.

#!/usr/bin/python
import math   # This will import math module

print "math.pow(100, 2) : ", math.pow(100, 2)
print "math.pow(100, -2) : ", math.pow(100, -2)
print "math.pow(2, 4) : ", math.pow(2, 4)
print "math.pow(3, 0) : ", math.pow(3, 0)

When we run above program, it produces following result −

math.pow(100, 2) :  10000.0
math.pow(100, -2) :  0.0001
math.pow(2, 4) :  16.0
math.pow(3, 0) :  1.0
