Infinite recursion with if statement in Python-CodePudding

I have this code:

def get_girlfriend():
  res = input("Will you go out with me? ")
  if (res == "y"):
    print("We've done it bois")
    return
  get_girlfriend()

but I keep getting this error:

RecursionError: maximum recursion depth exceeded

Could anyone help?

CodePudding user response：

Default recursion depth in python is 1000, but if you need to increase the depth (Not recommended) by;

import sys
sys.setrecursionlimit(needed_depth)

But if you're trying to run your simple program without any Error, try to capture them and handle or set a base limit for the recursion.

Set a base limit for recursion:

def get_girlfriend(n=0):
    res = input("Will you go out with me? ")
    if (n < 100 and res == "y"):
        print("We've done it bois")
        return
    get_girlfriend(n 1)

Try and Capture the Error:

def get_girlfriend():
    res = input("Will you go out with me? ")
    if (res == "y"):
        print("We've done it bois")
        return
    try:
        get_girlfriend()
    except RecursionError:
        return

A Function should always have an exit gateway.

CodePudding user response：

The default maximum recursion depth for python is 1000.

So when the function calls itself to 1000 times, you get the error. I do not know what you aim to achieve by your code but by adding some condition if the statement satisfies your condition, you will be able to terminate.

def get_girlfriend():
    res = input("Will you go out with me? ")
    answer = res
    if (answer == "y"):
        print("We've done it bois")

get_girlfriend()

idk if this what you mean. But here's the output if you type y

Will you go out with me? y We've done it bois

and others but y: Will you go out with me? n
