Practical application solution for creating command lines using Python applets

If you are confused about the actual operation steps of the Python applet, you can refer to the following article for a detailed understanding of the Python applet, this article describes how to use it to create your own command line Address Book Program and modify, delete, and search for your contacts and their information.

Because we need to do something about electronic chart display, we can see on the relevant forum that some Daniel said that the combination of GDAL and PIL can easily draw vector graphics. As the name implies, PILPython Imaging Library is built on Python, So I downloaded Python2.6 from the day before yesterday and read the Python Concise Manual. At the end of this manual, the author suggests that beginners develop such a program,

That is, create your own command line Address Book Program. In this program, you can add, modify, delete, and search for your contacts and their information. The details should be saved for future extraction.

After several hours of hard work, the Python applet code is as follows: By the way, Python is really better to use, but it is much easier than learning VC/MFC at the beginning, of course, it may be partly because you have already experienced c ++)
