Beginning Python (Video 33)

The video tutorial introduces the concept of recursion, explaining how functions can call themselves and the importance of the call stack and base cases. It provides two examples: a function that doubles a number and a function that calculates exponentiation using recursion. The tutorial emphasizes understanding the base case to stop recursive calls and how the call stack helps in summing up results. The video concludes with a brief summary and a preview of more examples in the next video.

Describe the process of calculating an exponent recursively.

What happens when the base case is reached in a recursive function?
