Hi,

It seems that sys.argv is not a sequence if there are
no args passed. Hence references to len() or
non-existent element sys.argv[1] cause a TypeError
which we have to kludge around with a try...except
TypeError. sys.argv should always be a sequence.

Python 1.6 (#4, Sep 13 2000, 17:24:07) [GCC
egcs-2.91.66 19990314 (egcs-1.1.2 release)] on sunos5
(Solaris 8)

Best regards,
Stephen

Can you provide an example of how you invoke Python with no
args and what value sys.argv[] has? I can't reproduce.
