python 的 zipfile 提供了非常便捷的方法来压缩和解压 zip 文件。
例如,在py脚本所在目录中,有如下文件:
复制代码 代码如下:
readability/readability.js
readability/readability.txt
readability/readability-print.css
readability/sprite-readability.png
readability/readability.css
readability/readability.txt
readability/readability-print.css
readability/sprite-readability.png
readability/readability.css
将 readability 目录中的文件压缩到脚本所在目录的 readability.zip 文件中,保持相同的文件结构,然后打印出生成的压缩包 的文件列表,再用两种方式分别解压文件到脚本所在目录的 output 目录和 output/bak 目录中。
脚本如下:
