A simple Alarm Clock using Python Tkinter | cool python project

This is a beginner practice project using python language. By this, the use of the Tkinter package will be learned by the python language reader. You have to install the Tkinter package before running the below code of the Alarm clock project. The installation process of the Tkinter package is defined below.

How to install Tkinter in windows and Linux OS?

# for pip3 in windows, write it in cmd:
pip3 install tk

# for python3 version in linux, write in cmd:
sudo apt-get install python3-tk 


# for pip and windows, write in cmd:
pip install tk

The Tkinter library is used in this project as the user interface (to add buttons, text, options, and others). The code is so simple. The traditional alarm clock code is fitted to the user interface.

Some screenshots of this project

1. Choose a time from option menus.

2. Hit the 'Set Alarm' button.

3. The code will run infinitely until the alarm time has been finished. See the console that the code gives output.
