Using Python to implement dynamic alarm clock

The main functions are as follows:
1. Use turtle and other graphics drawing libraries to draw a dynamic digital tube clock, in which the hours, minutes and seconds are distinguished by different colors.
2. Ability to set alarms through the keyboard and realize window pop-up reminders.
3. PassPyInstaller Convert the library into an executable file.

PyInstaller Library

PyInstaller is a library for packaging Python applications into standalone executables.

It can package Python scripts and related dependencies (such as libraries, resource files) into a single executable file, so that users can run the application without installing the Python interpreter or related libraries. PyInstaller can be used to easily create cross-platform executable files, supporting multiple platforms such as Windows, Mac, and Linux.

Run the example:

Set alarm:

Package the files first

Can be dragged to the desktop~

win+R, enter cmd

Enter in the command line, python clock.py 22-28

clock.py is the file name. If the file name is different, modify it according to the actual file name.
It means 22:28 reminder
