How to Use Python to compress and decompress zip files

This article mainly introduces how to use Python to compress and decompress zip files. It mainly uses the zipfile package. For more information, see

Python zipfile provides a very convenient way to compress and decompress zip files.

For example, in the directory where The py script is located, there are the following files:

The Code is as follows:

Readability/readability. js

Readability/readability.txt

Read/readability-print.css

Read/sprite-readability.png

Readability/readability.css

Compress the files in the readability directory to the readability.zip file in the script directory, maintain the same file structure, and then print the file list of the generated compressed package, decompress the file to the output directory and output/bak directory of the script directory in two ways.

The script is as follows:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42
