初始化期間python繼承函數覆蓋

Question

不知何故，Father類可以看到Child類的方法。我推測只有內部方法可用於父親初始

但顯然我錯了。下面是代碼：

class Father(): 
    def __init__(self): 
     self.name=self.getName() 
     print "from Father ->", self.name 

    def getName(self): 
     return "father" 

class Child(Father): 
    def __init__(self):   
     Father.__init__(self) 
     self.name=self.getName() 
     print "from Child ->", self.name 

    def getName(self): 
     return "child" 

if __name__ == "__main__": 
    import sys, pprint 

    someone=Child() 

，輸出是

from Father -> child 
from Child -> child 

但我想獲得

from Father -> father 
from Child -> child 

任何思考如何改寫呢？ Tnx！

這是name-mangling目的：它可以讓你說： 「這個類的屬性」：

class Father(): 
    def __init__(self): 
     self.name=self.__getName() 
     print "from Father ->", self.name 
    def __getName(self): 
     return "father" 

class Child(Father): 
    def __init__(self):   
     Father.__init__(self) 
     self.name=self.__getName() 
     print "from Child ->", self.name 

    def __getName(self): 
     return "child" 

if __name__ == "__main__": 
    import sys, pprint 

    someone=Child() 

產量

from Father -> father 
from Child -> child
