tarfile is a python library to read and write gzip`/`bz2 compressed files.

How to read a gzip compressed tar archive and display some member information:

import tarfile
 tar = tarfile.open("sample.tar.gz", "r:gz")
 for tarinfo in tar:
     print tarinfo.name, "is", tarinfo.size, "bytes in size and is",
     if tarinfo.isreg():
         print "a regular file."
     elif tarinfo.isdir():
         print "a directory."
     else:
         print "something else."
 tar.close()

Create a compressed file:

with tarfile.open(dst, "w:gz") as tar:
     print("Archiving " + src + " into " + dst)
     tar.add(src, arcname = os.path.basename(src))

NOTE: the flag of w:gz opens the destination in write mode. Used to create a new tar file.
