Recursive Power Calculation in Python

Calculating the power of a number is a common mathematical operation. In this guide, we'll explore how to find the power of a number using recursion in Python. Recursion is a programming technique where a function calls itself in its own definition.

Let's dive into the Python program to find the power of a number using recursion.

Let's break down the code:

The power function takes two parameters, base and exponent.

The base case checks if the exponent is 0, in which case the result is 1.

In the recursive case, the function multiplies the base by the result of the recursive call with a decremented exponent.

Finally, we input the values for the base and exponent, call the power function, and print the result.

For example, with base = 2 and exponent = 3, the output will be 2^3 = 8.

This program illustrates the concept of recursion by breaking down the problem into smaller subproblems until it reaches the base case. It's important to ensure that the base case is well-defined to avoid infinite recursion.

Feel free to modify the input values and observe the results for different base and exponent combinations.

Understanding recursion is a fundamental concept in programming, and this example provides a practical demonstration of its application in calculating powers.
