Recursion not working python

WebYou can resolve this by modifying the number of recursion calls such as: #!/usr/bin/env python import sys sys.setrecursionlimit (5000) def factorial(n): if n == 1: return 1 else: return n * factorial (n-1) print(factorial (3000)) but keep in mind there is still a limit to the input for the factorial function. You need a return before the recursive calls to iterated (e.g. return self.iterated(n/2)). If you don't explicitly return , the function will return None . That will fix this issue, but there is a way to make your code simpler: You don't actually need the member length .

WebAug 7, 2024 · It can be used for manipulating Python runtime environment. sys.setrecursionlimit () method is used to set the maximum depth of the Python interpreter stack to the required limit. This limit prevents any program from getting into infinite recursion, Otherwise infinite recursion will lead to overflow of the C stack and crash the … WebPython's stack is limited, so you should also make sure your recursive function is not growing the stack too large. This is usually not a problem for traversing things like filesystem trees, but probably is a problem for functions that recursively calculate things. You can see the limit with sys.getrecursionlimit (). It's 3000 on my machine. WebSep 5, 2024 · Recursion is confusing for beginner because instructors and tutorials often don't explicitly explain what the call stack is. The call stack is managed by the compiler or interpreter automatically in the background.
