I actually do have a copy of VisiCalc lying around, but I need a new power supply for my Apple ][e so that I can run it (http://oldapples.blogspot.com). I find Excel (or the TI-83, or other spreadsheet tool) to be a decent planning tool, and then once the project exceeds Excel's capabilities, I turn it into a relational database in Python. One huge thing to beware: Excel doesn't use the proper order of operations -- it evaluates exponents from left to right rather than from the top expression down. That is, 4^3^2 in Excel is (4^3)^2 where in Python, 4 ** 3 ** 2 is (properly) 4 ** (3 ** 2) the moral of the story is that programmers should ALWAYS use parentheses to avoid rude surprises. _______________________________________________ Edu-sig mailing list Edu-sig@python.org http://mail.python.org/mailman/listinfo/edu-sig
