Here I'm using it to compare the result of a function where I specifically return False on error condition, so I think it's better I check it against the literal False rather than the fuzzy False produced by the boolean operation. I wouldn't do this in most situations though, but I did need to distinguish between the the empty list and False and using the broader form as in "if not a" did not work as expected. -- Harishankar (http://harishankar.org http://lawstudentscommunity.com) -- http://mail.python.org/mailman/listinfo/python-list
