How Can I Handle Recursion Depth Limitations and Stack Overflow Errors in Python?

Recursion Depth Limitations and Overcoming Stack Overflow Errors

When working with recursive functions in Python, you may encounter a RecursionError due to reaching the maximum recursion depth. In this case, the error arises from the stack overflow caused by the function's unoptimized tail recursion.

To determine the maximum recursion depth, use sys.getrecursionlimit():

import sys
print(sys.getrecursionlimit())

You can change the recursion limit with sys.setrecursionlimit(), but be cautious as it can be dangerous.

sys.setrecursionlimit(1500)

However, it's crucial to note that Python is not a functional language, and tail recursion may not always be efficient. Iteratively rewriting the algorithm is often a better solution.
