- (define-pyslot NAME [SCHEME-NAME])syntax
Defines an accessor/modifier for the Python object attribute NAME. The optional argument SCHEME-NAME is an alternate name for the Scheme procedure. The returned procedure takes in a Python object and returns the value of attribute NAME contained in that object. If the object has no such attribute, #f is returned. If a value is supplied after the name of the object, the procedure acts as a modifier for that slot.
