As pointed out before, a big advantage of this convention is that it can be made absolutely consistent while avoiding clashes with Python builtins. So we can have Sum() without shadowing Python's sum(), Abs() without shadowing abs(), etc. Fredrik --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
