Unpacking archives

To unpack the archives, the shutil module has the unpack_archive() function. Using this function, we can extract the archive files. We passed the archive filename and the directory where we want to extract the contents. If no directory name is passed, then it will extract the contents into your current working directory.

Now, create a script called shutil_unpack_archive.py and write the following code in it:

import pathlibimport shutilimport sysimport tempfilewith tempfile.TemporaryDirectory() as d: shutil.unpack_archive('work_sample.tar.gz', extract_dir='/home/student/work',) prefix_len = len(d) + 1 for extracted in pathlib.Path(d).rglob('*'): print(str(extracted)[prefix_len:])

Run the script as follows:

student@ubuntu:~/work$ ...
