zipfile.ZipFile is first opened in write mode with the ZIP_DEFLATED compression (which means compress the data with the standard ZIP format) as a context. That allows us to perform changes to the archive and then flush them and close the archive automatically as soon as we exit the body of the context manager.

Within the context, we rely on os.walk to traverse the whole directory and all its subdirectories and find all the contained files.

For each file found in each directory, we build two paths: the absolute one and the relative one.

The absolute one is required to tell ZipFile from where to read the data that needs to be added to the archive, and the relative one is used to give a proper name to the data we are writing ...
