math.pow( x, y )

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 -- This is a numeric expression.

• y -- This is also a numeric expression.

This method returns value of x^y.

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)

Let us compile and run the above program, this will produce the 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
