How do I get rid of the ' the program is still running are you sure you want to kill it' warning on python?

Question

print ('Password Request Initiative')

password = 'abcd'
user_input = input('Please Enter Password: ')

if user_input != password:
    print("Haha. Nope") 
    quit()

elif user_input == password:
            print ("User is now logged in...")
    enter code here

that's the code, but when I run it and type the wrong password it shows this warning: And I want it to run without this message so it just instantly closes

Answer 1

To avoid the message when running from IDLE, do not use quit() or exit() in a program. They are not part of the language and are not intended for this use. They are (usually) added by the site package for interactive use only . In particular, they were added so that people could more easily exit the interactive interpreter when running in a terminal window -- without knowing the magic control code needed on a particular system -- and without closing the terminal window itself.

C:\Users\Terry>python
Python 3.5.1 ... [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> ^D
SyntaxError: invalid syntax
>>> ^Z

On Unix, ^D , End of File, exits, but on DOS and still on Windows, ^Z<Return> is used instead. Few beginners know this. Other interactive programs use quit and exit , so we added those as synonyms.

With IDLE, ^D in the shell closes the shell on all systems, but not editor windows. It is the same as clicking the close button on the title bar. At least on Windows, ^Q == quit() and closes everything.

To exit a program when not as the bottom of a file, use raise SystemExit or sys.exit() .

As the expansion of the acronym says, IDLE is a development environment. It is a feature of IDLE that testing a program within IDLE does not kill IDLE itself, at least not without warning.
