Python Number pow() Method
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
