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 the 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 represents 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 the pow() function in Python. This program uses all three parameters of the 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. pow(5, 3, 10) gives 5. pow(2, 6, 10) gets evaluated as (26) % 10, then 64%10, and then 4. Therefore, pow(2, 6, 10) gives 4.
