# What is the use of the "pow" function in Python?

The `**pow**`

function in Python calculates the power of a number, i.e., it returns the result of the first argument raised to the power of the second argument. The function has two required arguments: the first argument is the number being raised to the power and the second argument is the power to which the first argument is raised. An optional third argument can be passed to `**pow**`

, which represents the modulus.

The `**pow**`

function can be used as follows:

```
>>> pow(2, 3)
8
>>> pow(2, 3, 5)
3
```

Here, `**pow(2, 3)**`

returns 8, which is 2 raised to the power of 3, and `**pow(2, 3, 5)**`

returns 3, which is the remainder of `**pow(2, 3)**`

divided by 5.
