I think the summary is correct (am not going to bother to double- check), but there's a subtle point you're missing. Here is a simplified explanation. The syntax for subscript operator is: expression [ expression ] The syntax for attribute access is: expression . symbol The subtle point here is that the symbol that comes after the dot is NOT an expression, and therefore can't serve as the first expression in the subscript opreator rules. The effect of this is that the grouping a.(b[c]) is impossible. Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
