Python pow() Function

The pow() function in Python is used when we need to find the value of x to the power of y. For example:

x = 2
y = 4
print(pow(x, y))

The output will be:

16

That is, xy or 24 or 2*2*2*2 is equal to 16.

Python pow() Function Syntax

The syntax of pow() function in Python, is:

pow(base, exponent, mod)

where base refers to a number representing the base value, exponent also refers to a number, but representing the exponent value. And mod is used when we need to calculate the modulus of baseexponent.

Python pow() Function Example

Here is an example of pow() function in Python. This program uses all the three parameters of pow() function:

print(pow(2, 4, 3))
print(pow(5, 3, 10))
print(pow(2, 6, 10))

The output will be:

1
5
4

That is, pow(2, 4, 3) gets evaluated as (24) % 3, then (16%3), then 1. Therefore pow(2, 4, 3) gives 1. Similarly, pow(5, 3, 10) gets evaluated as (53) % 10, then 125%10, then 5. Therefore pow(5, 3, 10) gives 5. And pow(2, 6, 10) gets evaluated as (26) % 10 then 64%10 then 4. Therefore pow(2, 6, 10) gives 4.
