Since too many contents and instructions are involved in the code, we will not cover every
detail. For more knowledge about Python 2, Python 3, PyQt, Django, HTML, and CSS in the
programs, you can visit related websites or buy books to learn by yourself. In the following
part, we will go through the overall structure and the process in brief.
First, let’s check the files in the code folder:
￭ .git is a hidden directory to store all the information of a Git repository; it's generated
automatically after you create the repository.
