Hello, I am new to Python. I am having trouble with zipfile.py.
On a Linux machine with python 2.4.2 I have trouble opening a zipfile. Python is complaining about the bit where it does a seek(-22,2). Looks to me like zipfile.py is trying to come back 22 bytes from the end of file. # python Python 2.4.2 (#1, Oct 27 2005, 15:13:45) [GCC 3.3.3 20040412 (Red Hat Linux 3.3.3-7)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import zipfile >>> zf=zipfile.ZipFile("testdoc.odt") Traceback (most recent call last): File "<stdin>", line 1, in ?
