Windows-toast is a Python library used for sending notifications in Windows 10 and 11. With it, you can even customize it to what you want it to be. Here's an example of a code:

>>> from windows_toasts import WindowsToaster, ToastText1
>>> wintoaster = WindowsToaster('Python')
>>> newToast = ToastText1()
>>> newToast.SetBody('Hello, world!')
>>> newToast.on_activated = lambda _: print('Toast clicked!')
>>> wintoaster.show_toast(newToast)
