How can I debug a recursive function in Python?

Debugging recursive functions can be tricky. You can use print statements to trace the flow of execution.

What if the function is too deep and I can't see all the print outputs?

In that case, consider using a debugger tool like pdb, which allows you to step through the code.

Can you show me an example of using pdb with a recursive function?

Sure! You can set breakpoints in your recursive function and inspect variables at each level of recursion.

Are there any common pitfalls I should be aware of when debugging?

Yes, common pitfalls include infinite recursion and incorrect base cases, which can lead to stack overflow.
