父類(lèi)調(diào)用子類(lèi)的屬性？？？？？
class?Preson(object): ????pass class?Student(Preson): ????pass class?Teacher(Preson): ????pass class?SkillMixin(object): ????pass class?Bstudent(Basketball,Student): ????pass class?Fteacher(Fotball,Teacher): ????pass print(s.skill()) print(t.skill())

當(dāng)子類(lèi)沒(méi)有def who(self)函數(shù) 此時(shí)可以使用父類(lèi)的def who(self)函數(shù) 如果子類(lèi)本身有就不用了
