A 'RecursionError' occurs when the maximum recursion depth is exceeded, typically due to an infinite recursion. Check your recursive function to ensure there’s a proper base case to terminate the recursion.

The 'RecursionError' is an exception that occurs in Python when a program exceeds the maximum recursion depth, which is usually set to 1000 by default. This often happens in scenarios where a recursive function lacks a proper base case or if the base case is never reached, leading to infinite recursion. To resolve this error, first, examine your recursive function to ensure that there is a clear and correct base case defined. The base case should specify the condition under which the recursion will stop and should be reachable with the input values provided. For instance, if you are implementing a function to compute the factorial of a number, ensure that there is a condition that stops the recursion when the input reaches 1 or 0. If your logic is sound but the recursion depth is too deep for your use case, consider refactoring the recursive algorithm into an iterative one, which may be more efficient and less prone to depth limitations. Additionally, Python provides the sys module, which allows you to adjust the recursion limit using sys.setrecursionlimit(), but this should be done with caution as it may lead to increased memory usage. By addressing these points, you can effectively manage and troubleshoot RecursionErrors in your Python applications.
