Why I can't exit code in python?

Question

I've tried use exit(), exit(0), sys.exit()(I've import sys) and quit(), but none of them can help me to exit code.

Here is my code when using exit():

from pystray import MenuItem as item
import pystray
from PIL import Image


while True:
    def show():
        exit()
    image = Image.open("TrayIcon.jpg")
    menu = (item('exit', show),)
    icon = pystray.Icon("name", image, "title", menu)
    icon.run()
    print('running...')

This is the error when using exit()

An error occurred when calling message handler
Traceback (most recent call last):

    raise SystemExit(code)
SystemExit: None

i aslo have tried to turn

from pystray import MenuItem as item
import pystray
from PIL import Image


def show():
    icon.stop()


image = Image.open("TrayIcon.jpg")
menu = (item('exit', show),)
icon = pystray.Icon("name", image, "title", menu)
icon.run()

while True:
    print('running...')

At this time, i can't running... is not show when the icon is in the tray, i must exit it to show.

Other errors are quiet similar with the error when using exit()

Answer 1

I've given this a test now and you don't need to call exit(). Instead, call icon.stop()

Also, no need for the infinite loop!

from pystray import MenuItem as item
import pystray
from PIL import Image

def show():
    icon.stop()
    
image = Image.open("TrayIcon.jpg")
menu = (item('exit', show),)
icon = pystray.Icon("name", image, "title", menu)
icon.run()

To exit the shell and return to the system prompt, type exit() or Ctrl-D.
