Thank for the reply. The tar file is not corrupted, i am using the same file in 32-bit m/c and able to extract it. I have attached this output also with the mail. I am getting this problem only in 64-bit m/c.
output from 32-bit m/c: tarfile.is_tarfile(tar) func <bound method type.gzopen of <class 'tarfile.TarFile'>> func1 <tarfile.TarFile object at 0xb7f028ac> True For reference i have tested the same in different systems. -- Thanks & Regards V.Murugadoss On Fri, Jun 4, 2010 at 7:35 PM, Anand Balachandran Pillai < [email protected]> wrote: > On Fri, Jun 4, 2010 at 11:27 AM, murugadoss <[email protected] > >wrote: > > > Hello, > > > > I am trying to extract a tar file. while doing this i check the valid tar > > file using is_tarfile( ). > > It is working fine in a 32-bit linux machine with python 2.5.4 version > and > > when i try it out in a 64-bit linux pc, i end up saying file is > > invalid(false).
