How can I use an alert dialog with Python in linux?

Question

My question is similar to this question, but I'm using Xubuntu, so the win32 api is obviously not available. Is there some alternative I can use?

I just need to have a simple window pop up with a message, from a python script.

To create a notification rather than a dialog box that needs to be dismissed, you can use notify-send as shown below. This also does not require installing python-tk or other packages.

import subprocess
subprocess.run(["/usr/bin/notify-send", "--icon=error", "This is your error message ..."])

See the man page for more options.
