Have you Read The Fine Manual at the Fine Website? Try typing "Python documentation" into your favourite search engine, or try going to http://www.python.org/ which links directly to http://www.python.org/doc/ Unfortunately, searching for operators is always tricky (try searching for "*" some day...) but the section you want is here: http://docs.python.org/ref/augassign.html Also, it isn't always true that a += b is not the same as a = a+b. It depends on what a and b are. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
