A long time ago (27 days I was asked to write a script to retrieve and extract all tar files named in a specific format on the disk, so I started learning and fishing together.

The script to be written this time aims at the following file structure:

The file structure is shown in the figure above

You can see that there are two tgz compression packages in a tar package. I need to complete the work as shown in the following figure:

PressOn is a good thing

In Python, there are two packages that can call system instructions, one is called sys and the other is called os. What's better is that they don't distinguish operating systems at the high-level language level. The same variable curdir can get the available paths for this operating system under linux and win. os.system() or os.popen() can change the parameters in brackets into the instructions used by the system, as long as the instructions given are correct.

I learned some new things in this script writing, and I can record them here for my own reference.
