Hi, When I search around tutorial about None, I came across this link:
http://jaredgrubb.blogspot.ca/2009/04/python-is-none-vs-none.html I don't understand what use of this class example: >>> class Zero(): # a class that is zero ... def __nonzero__(self): ... return False I can only get the following code running: cz1=Zero() cz1.__nonzero__() Out[119]: False Here are my questions: 1. Is there any other means to use class Zero? 2. What connection to None on the original author's intention? Thanks, -- https://mail.python.org/mailman/listinfo/python-list
