I think I would rewrite the current unit-testing example to use the standard library unittest module:: # Let's write reusable code, and unit test it. def add_money(amounts): # do arithmetic in pennies so as not to accumulate float errors pennies = sum([round(int(amount * 100)) for amount in amounts]) return float(pennies / 100.0) import unittest class TestAddMoney(unittest.TestCase): def test_float_errors(self): self.failUnlessEqual(add_money([0.13, 0.02]), 0.15) self.failUnlessEqual(add_money([100.01, 99.99]), 200) self.failUnlessEqual(add_money([0, -13.00, 13.00]), 0) if __name__ == '__main__': unittest.main() I believe I've still kept it to 13 lines. STeVe P.S. The "right" way to add money is using the decimal module, but I couldn't think of a better example. -- http://mail.python.org/mailman/listinfo/python-list
