It could, but it would need some magic. A lot of test frameworks have their own set of assertions and you have to pick the one you want - for instance: assertEqual(x, y) instead of assert x == y The trouble is that, if you write a function for this, it will just get True or False, without any explanation of the cause - making it somewhat unhelpful when something goes wrong. To compensate, function equivalents inevitably have to have myriad types of assertions, where the language just needs one. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
