Recursive looping to n levels in Python

In this tutorial, we will explore the concept of recursion and how to create recursive loops that can go to N levels in Python. Recursive functions are a powerful technique in programming where a function calls itself to solve a problem. We will use Python for this tutorial, and by the end, you'll have a good understanding of how to implement recursive loops to traverse nested structures to N levels.
Recursion is a technique in which a function solves a problem by making one or more calls to itself. It's a way of breaking down a complex problem into simpler, similar subproblems. Each recursive call should make progress towards solving the problem and eventually reach a base case that stops the recursion.
A recursive function typically has two components:
Base Case: The base case is the condition that stops the recursion. It is the simplest case where the function returns a value without making further recursive calls. Without a base case, the recursive function would run infinitely.
Recursive Case: The recursive case is where the function calls itself with modified arguments to solve a smaller subproblem. This call should be closer to the base case than the previous call.
To loop recursively to N levels, you need to design your recursive function in such a way that it iterates through a nested structure or performs an action N times, decrementing N with each recursive call until the base case is reached.
The base case for looping N levels is usually when N reaches 0. At this point, the function should stop making recursive calls and return.
