I'm running into a something unexpected for a new-style class that has both a class attribute and __slots__ defined. If the name of the class attribute also exists in __slots__, Python throws an AttributeError. Is this by design (if so, why)?
class A( object ): __slots__ = ( 'value', ) value = 1 def __init__( self, value = None ): self.value = value or A.value a = A() print a.value Traceback (most recent call last): File "t1.py", line 8, in ? a = A() File "t1.py", line 6, in __init__ self.value = value or A.value AttributeError: 'A' object attribute 'value' is read-only -- http://mail.python.org/mailman/listinfo/python-list
