Use Python to write your own Simple zip compression software with a complete picture (suitable for beginners), pythonzip
I. Software Description

Use the Python tkinter module to write your own compression software. The zip file format is a common document compression standard. In the ziplib module, ZipFile is used to operate zip files. It has the following functions: zip compression and zip decompression. (Fewer features, relatively low, Do not spray .)

Ii. required knowledge points

• Use of functions
• Use of global variables
• Tkinter Module
• Zip Module
