The current bz2 module only supports files written as a single stream, and not multiple stream files. This is why the BZ2File class has no "append" mode. See this bug report: http://bugs.python.org/issue1625 Here's an example: >>> bz2.BZ2File('a.bz2', 'w').write('this is the first chunk of text') >>> bz2.BZ2File('b.bz2', 'w').write('this is the second chunk of text') >>> bz2.BZ2File('c.bz2', 'w').write('this is the third chunk of text') >>> # concatenate the files ... d = file('concate.bz2', 'w') >>> for name in "abc": ... f = file('%c.bz2' % name, 'rb') ... d.write(f.read()) ... >>> d.close() >>> >>> bz2.BZ2File('concate.bz2', 'r').read() 'this is the first chunk of text' Sure enough, BZ2File only sees the first chunk of text, but if I open it in (e.g.) KDE's Ark application, I see all the text. So this is a known bug, sorry. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
