Two options: instantiate all attributes, or ones with a certain property, such as name or superclass. class C: inst_d= D #actually gets bound to 'd', optionally class C: d= inst( D ) I think what I'm looking for is an attribute wrapper. class C: @inst d= D But the closest the syntax goes is: class C: class d( D ): pass (which takes us back to one of Steven's posts some days ago.) ( def f(x=None):/class C:/x= X/return C. ) and the d= inst( D ) solution.) You either need to assign something to assign something to its name, class C: d= X or declare it, but that only allows def and class statements (correct?). class C: attr d: D is ideal. -- http://mail.python.org/mailman/listinfo/python-list
