Desktop Notifier Project (code) in Python

Desktop Notifier in Python.

About the project: This is a Desktop Notifier project in Python. This will be a standalone script that sends custom notifications to your desktop.

For this project, we'll use the plyer library, which provides a cross-platform way to access features like notifications. This will work on Windows, macOS, and Linux.

Some operating systems may require additional dependencies. For example, on Windows, win10toast might be used, and on Linux, libnotify is a common dependency.

How to use this program:

To use this Desktop Notifier, you'll first need to install the plyer library. Open your terminal or command prompt and run:


    pip install plyer

Once installed, you can run the Python script:

Run the Python script.
The program will ask you to enter a notification title and a notification message.
The program will then send the notification to your desktop.
You can keep creating and sending new notifications until you type q to quit at any prompt.
