This means that each call to your recursive function will create a function call stack and because there is a limit of stack. It means the function will stop when it finds an answer or a specific condition is met. The way I create the flask app is the following. Which requires more work to stop-a light truck or a heavy truck moving with the same momentum? As we already know, recursive functions call by itself directly or indirectly, and during this process, the execution . So, lets define a Python list that contains a few numbers. Before doing so, lets check the recursion depth in python in the below code example: Here, you can see that the limit of the recursion depth in python is 1000 and if we cross this limit then that error will occur.

I don't know zilch about odoo, but hopefully there must be a way to set a field without triggering a call to write - else, well, bad luck. We are basically going from recursion to iteration. To get over this limitation, you can set the recursion limit using the setrecursionlimit () function. When recursive calls are made, then with memoization we can store the previously calculated values instead of unnecessarily calculating them again. You might have seen a Python recursion error when running your Python code. A function that calls itself is a recursive function in Python. I don't think you are supposed to call ctx.pop() in your teardown function as the call to pop() invokes the registered teardown callbacks (hence the infinite recurAppContext calls Flask.do_teardown_appcontext() which contains the following: You should call ctx.pop() when you are destroying your fixture. Apparently, related to #715 , the issue was being caused because I use flask-babel in the project. MatchAllFilter maf = new MatchAllFilter(); Using the sys library, we will use the sys.setrecursionlimit() function. Also, recursion can lead to an infinite loop, if the base case is not met in the calls. python - python - Already on GitHub?
