Timer Application using PyQt5

This tutorial will demonstrate how to build a timer application using PyQt5. A timer is indeed a special kind of clock that is used to measure certain time intervals; to use one, count downwards from the provided time until it equals zero.

Steps for Implementing a GUI:

1. Make a push button that will activate a pop-up clock and configure its geometry.
2. Produce a label to display the time and the completion status
3. Centre the label's text and adjust the label's shape and font size.
4. Design three push buttons: one to start the timer, one to pause it, and one to reset it.
5. Adjust the button geometry.

Back-end Steps for Implementation:

1. Create a count variable and a flag to indicate whether the counter is running or not.
2. Give each button a function.
3. Get the value of the second using the input dialogue box within the acquire second button action, and set the flag to false.
4. Make flag true inside of the start action but make if false if count is zero.
5. Make the flag false inside the pause action.
6. Inside the restore action, set the text to the label, the count value to zero, and the flag to false.
7. Create an object called a timer that calls its function every 100 milliseconds.
8. In the timer action, look for the flag, decrease the value of the count, and set the label's content.
