class nemo_export.tarutils.TarPath( tar: Union[str, tarfile.TarFile, nemo_export.tarutils.TarPath], *parts, )[source]#

A class that represents a path inside a TAR archive and behaves like pathlib.Path.

Expected use is to create a TarPath for the root of the archive first, and then derive paths to other files or directories inside the archive like so:

with TarPath(‘/path/to/archive.tar’) as archive: myfile = archive / ‘filename.txt’ if myfile.exists(): data = myfile.read() …

Only read and enumeration operations are supported.
