python - 初始化期间的python继承函数覆盖

Question

不知何故，Father 类可以看到 Child 类的方法。我假设在初始化期间只有内部方法可供父亲使用

但显然我错了。这是代码：

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()

输出是

from Father -> child
from Child -> child

但我想得到

from Father -> father
from Child -> child

任何想法如何重写它？天呐！

这是名称修改的目的：它允许您说：“此类的属性”：

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()

产量

from Father -> father
from Child -> child
