RE: [Zope] Future watch: how will python division change affectzo pe?
I think Guido is right in his idea that this should be integrated in 3.0+, so this SHOULD NOT be that big of a deal. That will keep it far off enough that it will not have a severe impact. I think fixing a design bug in the language and just getting it done with is a good thing... Integer division operator // will be integrated into 2.2 to allow for us to start writing good code premptively before 3.0...

I'm not sure about everyone's idea on this, but Backward Compatibility is a Good Thing(tm). Why don't we just say: 1/2 == 0 1//2 == 0.5 Troy -----Original Message----- From: Steve Drees [mailto:drees@the-bridge.net] Sent: Thursday, July 26, 2001 8:56 AM To: Dieter Maurer; Chris Withers Cc: marc lindahl; zope@zope.org Subject: RE: [Zope] Future watch: how will python division change affectzope?

Go to agree with that. What are the reasons _for_ doing this? Most people without knowledge of "C" derived programming languages are astonished that "1/2" can be "0".
Marc & Chris are wrong here. Every 3rd grader in the US knows that 1/2 is not 0. So I would say that (american) english agrees with the proposed new division rules in python. _______________________________________________ Zope maillist - Zope@zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev ) _______________________________________________ Zope maillist - Zope@zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
We're not talking about third graders, we're talking about 7th graders and up - C programmers, C++, Java, even BASIC. They "know" that 1/2==0, but that 1.0/2 == 1/2.0 == 0.5. This is because, mathematically, the numeric representation is really floor(1.0/2.0). These are the people that will be programming Python, not english majors. English is not a programming language.

I want everybody to use python. Not just C programmers.
