PyautoGUI- How to use If - Else with pyautogui.locateCenterOnScreen

[Tiel]

Essentially I want my Python script to perform this...

1 2 3 4 5

x = True if x  == True:     print('Congratulations, you won!') else:     print('I'm sorry but you lost.')

with this...

1	a, b = pyautogui.locateCenterOnScreen('~/home/file_01.png', region=(1065,250,385,700), confidence=0.9)

In other words, how can I have my script check to see if PyautoGUI has successfully located the center of ~/home/file_01.png?

See, about 95% of the time the following works correctly....

1	a, b = pyautogui.locateCenterOnScreen('~/home/file_01.png', region=(1065,250,385,700), confidence=0.9)

But about 5% of the time ~/home/file_01.png does not exist. In those cases my script stops and throws off the following error message...

1	TypeError: cannot unpack non-iterable NoneType object

Instead of having my script stops in cases when ~/home/file_01.png does not exist I would prefer that my script skip that instance. In other words, instead of stopping I want my script to ignore cases when ~/home/file_01.png does not exist.

The cause is that pyautogui.locateCenterOnScreen return a Point object or None if the image was not found on screen.

You already got the right Exception, which you can catch.

1 2 3 4 5 6 7 8 9 10 11 12 13

import pyautogui     try:     x, y = pyautogui.locateCenterOnScreen("your_image.png") except TypeError:     print("Could not locate the image")     # this is only executed, if a TypeError was caught     # for example you can exit here with sys.exit(1)     # or with raise SystemExit("Sorry, image not found") else:     # this block is executed, if no exception happened     print(f"All fine, got the coordinates: {x} | {y}")

Thank you very much!

Your solution worked perfectly on my first two tries.

First I ran your solution without the image visible and second, of course, I ran it with the image visible.

Here is an additional naive solution without using Exceptions:

1 2 3 4 5 6 7 8 9 10

import pyautogui    coords = pyautogui.locateCenterOnScreen("your_image.png")   # coords is None -> no result if coords is None:     print("Could not locate the image") else:     x, y = coords  # tuple unpacking     print(f"All fine, got the coordinates: {x} | {y}")
