Why there is an error occurred by pystary in my programme (AttributeError: 'Icon' object has no attribute '_running')

An error occurred by pystary

My coding enviroment：windows10, python3.7

I want to make a tray application.But an error occurred.

Here is my code:

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


def show():
    print(":D")

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

Here is the error:

Traceback (most recent call last):
  File "C:/Users/admin/AppData/Roaming/JetBrains/PyCharmCE2022.1/scratches/scratch.py", line 12, in <module>
    icon = pystray.Icon("name", image, "title", menu)

    if self._running:

Solution

menu must be an iterable (a list or a tuple) but currently it is just a single item. You need to add a comma to make it a tuple:

menu = (item('print(":D")', show),)

In python, (42) is just the number 42, but (42,) is a tuple -- an iterable object -- containing the number 42.
