Until that one it works fine. Modify the main of your program as follows: Note: before executing the program remember to comment the line we have added in the section before that increases the recursion limit for the Python interpreter. . For example, heres a modified countup() function that uses the iterative approach: You can use the base case as the condition that tells the while loop when to stop, and do the required operations inside the while block. # Note that we must not import *anything* before the patch. Connect and share knowledge within a single location that is structured and easy to search. All recursive functions need an escape clause. The app is basically a portfolio generator based on python + flask. Merge Without Extra Space. The for loop will execute for a length equal to the value of the factorial number. The reason why the Python interpreter limits the number of times recursion can be performed is to avoid infinite recursion and hence avoid a stack overflow.
