What are the best practices for using recursion in Python?

What are the best practices for using recursion in Python?

Some best practices include ensuring a base case, avoiding deep recursion, and using memoization for efficiency.

Can you explain why having a base case is important?

A base case prevents infinite recursion by providing a condition under which the function stops calling itself.

What are some common pitfalls to avoid with recursion?

Common pitfalls include forgetting the base case, excessive memory usage, and stack overflow errors due to deep recursion.

How can I optimize a recursive function?

You can optimize it by using techniques like memoization, tail recursion, or converting it to an iterative approach.
