Python is not Java. In Python, classes are first-class objects (no pun intended) and can be assigned to variables the same as any other type. x = something_that_returns_a_float() # x is a float variable s = something_that_returns_a_string() # s is a string variable C = something_that_returns_a_class() # C is a class variable Preferred terminology is attribute, not variable. Class attributes live in the class and are shared across all instances. Instance attributes live in the instance and are not shared.
The subclass gets a shallow copy of the parent class namespace.
Not so much. py> class C(object): ... x = 1 ... py> class D(C): pass ... py> D.__dict__ == C.__dict__ False py> 'x' in D.__dict__ False -- Steven _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
