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, x^y 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 base^exponent.

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.
