How To Kill A Program In Python

I'm trying to kill a program in python 3 when the user says 'no' to start a maths quiz, : here is the code I'm using import sys while True: new_item = input('> ') if ne

Solution 1:

Your problem is here:

if new_item == "Yes" or "yes":

You need to use either:

if new_item in ["Yes", "yes"]:

or:

if new_item == "Yes" or new_item == "yes"

Your original code is parsed as:

if (new_item == "Yes") or "yes":

and this always evaluates to True since "yes" is a true value.

Solution 2:

if new_item == "Yes" or "yes":

This conditional is always True. It may be stated as:

(new_item == "Yes") or ("yes")

Non-empty string 'yes' is always evaluated to True.

Change conditional to:

if new_item in ['Yes', 'yes']:

Solution 3:

You need to change your if statement, it isn't evaluating properly. You need to use this code to fix your problem:

import sys

while True:
    new_item = input("> ")
    if new_item == "Yes" or new_item == "yes":
        break
    elif new_item == "no":
        sys.exit()

Solution 4:

What about

import sys

while True:
    new_item = input("> ")
    new_item = new_item.lower() 
    #everything you wrote in input will be lowercase, no more "or" problems
    if new_item.lower() == "yes":
        break
    elif new_item.lower() == "no":
        sys.exit()
