In any case, the *right* test would be: a = 1 assert a == 1 and a*5==5 and str(a)=='1' and [None,a,None][a] is a *wink* > At least, I usually ameliorate the pain a little bit by not bothering to > print any debugging information at the assertions until one of them > actually fails; otherwise I'd *never* get any real coding done :-) Ditto. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
