The Python RecursionError occurs when a function exceeds the maximum recursion depth due to the lack of a proper stopping condition or base case in a recursive function. This error arises when a recursive function calls itself repeatedly without a terminating condition, leading to an infinite loop until the recursion limit is exceeded. To fix a RecursionError, one can add a base case to stop the recursion, increase the recursion limit with caution using sys.setrecursionlimit(n), or use an iterative approach like loops to avoid recursion altogether and potentially improve code efficiency. Additionally, tools like Rollbar can be used for real-time error tracking, analysis, and management, which helps developers confidently deploy production code by automating error monitoring and triaging.
