The pow() method in Python number returns x to the power of y. If in case the third argument (z) is provided, then it functions as i.e. pow(x, y) % z i.e. it returns x to the power of y modulus z. This function in Python is used when an individual requires to derive the power of variable x to the variable y. If in a specified situation, the user may include a third variable which is z into the equation, and then the pow() method in Python number returns x to the power of y, modulus of z. In mathematical terms, this looks somewhat like this, pow(x, y) % z.
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 the math module, and then we need to call this function using a math static object.
This method returns the value of xy.
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 the above program, it produces 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
