Big file compression with python

Your script seems correct, but can be abbreviated:

from shutil import copyfileobj

with open('bigInputfile.txt', 'rb') as input:
    with bz2.BZ2File('bigInputfile.txt.bz2', 'wb', compresslevel=9) as output:
        copyfileobj(input, output)

Why are you calling the .close() methods? They are not needed as you use the with: statement.
