Tar

Gz

Gz typically compresses only one file, all of which often work with other packaging tools. For example, you can package it to X.tar with tar, and then compress it to X.tar.gz.

To extract gz is to actually read out a single file. The Python method is as follows:

Rar

Since rar is usually used under window, an additional Python package rarfile is required.

Look up the package

Pip search

Delete package

Pip uninstall or pip uninstall-r requirements.txt

View package information

Pip show

Check whether package dependencies are complete
