Because you imported it into the namespace, which is what the import statement does. dir() shows you what's in the namesace; therefore it lists x. dir() doesn't care, and can't know, if something was defined in a namespace, or merely imported. If it bothers you, you can put "del x" after the class y definition, but I recommend against doing that in general. If there's a reference to x inside a function that function will raise an exception if called, because it expects x to be inside the namespace.
