How can recursion be implemented in Python functions?

In Python, recursive function calls are implemented by the function calling itself from within the function. The specific steps are as follows:

1. Create a function that includes a call to itself within the function.
2. Within the function, use conditional statements to control the termination condition of recursion, known as the base case.
3. In recursive calls, pass the appropriate parameters to change the behavior of the function with each call.
4. Recursive calling involves repeatedly running the code of a function until the termination condition is met, and then returning the results layer by layer.

It is important to ensure that recursion can terminate within a finite number of steps when using it, otherwise it may lead to the issue of infinite recursion.
