Python's standard lib zipfile handles multiple files and has supported bz2 compression since 2001.

import zipfile
sourcefiles = ['a.txt', 'b.txt']
with zipfile.ZipFile('out.zip', 'w') as outputfile:
   for sourcefile in sourcefiles:
      outputfile.write(sourcefile, compress_type=zipfile.ZIP_BZIP2)

you have import package for:

import tarfile,bz2

and multilfile compress in bz format

tar = tarfile.open("save the directory.tar.bz", "w:bz2")
for f in ["gti.png","gti.txt","file.taz"]:
    tar.add(os.path.basename(f))
tar.close()

let use for in zip format was open in a directory open file

an use

os.path.basename(src_file)

open a only for file

This is what tarballs are for. The tar format packs the files together, then you compress the result. Python makes it easy to do both at once with the tarfile module, where passing a "mode" of 'w:bz2' opens a new tar file for write with seamless bz2 compression. Super-simple example:

import tarfile

with tarfile.open('mytar.tar.bz2', 'w:bz2') as tar:
    for file in mylistoffiles:
        tar.add(file)

If you don't need much control over the operation, shutil.make_archive might be a possible alternative, which would simplify the code for compressing a whole directory tree to:

shutil.make_archive('mytar', 'bztar', directory_to_compress)

Take a look at python's bz2 library. Make sure to google and read the docs first!
