# Python program to find the power of a number using recursion

• Last Updated : 06 May, 2021

Given a number N and power P. The task is to write a Python program to find the power of a number using recursion.

Definition: The power of a number can be defined as multiplication of the number repetitively the number of times of its power.

Example:

```Input: N=2 , P=3
Output: 8

Input: N=5 , P=2
Output: 25
```

The idea is to calculate power of a number ‘N’ is to multiply that number ‘P’ times i.e In first example N=2 and P=3, we are getting the result by multiplying 2 three times repetitively which gives us output 8.

Below is the implementation:

## Python

 `def` `power(N, P):`` ` `    ``# if power is 0 then return 1``    ``if` `P ``=``=` `0``:``        ``return` `1``     ` `    ``# if power is 1 then number is``    ``# returned``    ``elif` `P ``=``=` `1``:``        ``return` `N``     ` `    ``else``:``        ``return` `(N``*``power(N, P``-``1``))`` ` `# Driver program``N ``=` `5``P ``=` `2`` ` `print``(power(N, P))`

Output:

```25
```
