Yes, infix is better ( and note that Math uses primarly infix notation for common operators ) because you have a clear view of the evaluation tree that way. With prefix or postfix notation, you need to parse the full expression to find what goes to the first parameter of that +, and what goes to the second parameter. I would say that prefix/postfix is somewhat easier to write, but that infix is far far far easier to read. -- http://mail.python.org/mailman/listinfo/python-list
