使用 super() 与非直接父级
这是 super() 的合法使用吗？
class A(object):
def method(self, arg):
pass
class B(A):
def method(self, arg):
super(B,self).method(arg)
class C(B):
def method(self, arg):
super(B,self).method(arg)
谢谢。
Is this a legal use of super()?
class A(object):
def method(self, arg):
pass
class B(A):
def method(self, arg):
super(B,self).method(arg)
class C(B):
def method(self, arg):
super(B,self).method(arg)
Thank you.

它会起作用，但它可能会让任何试图阅读你的代码的人感到困惑（包括你，除非你特别记得它）。不要忘记，如果您想从特定父类调用方法，您可以这样做：
It will work, but it will probably confuse anyone trying to read your code (including you, unless you remember it specifically). Don't forget that if you want to call a method from a particular parent class, you can just do:
嗯，“合法”在这里是一个值得商榷的术语。该代码最终将调用
A.method，因为赋予super的类型被排除在搜索之外。至少可以说，我认为 super 的这种用法很不稳定，因为它会跳过继承层次结构的一个成员（看似随意），这与我作为开发人员的期望不一致。由于已经鼓励super的用户保持一致性，因此我建议不要这种做法。Well, "legal" is a questionable term here. The code will end up calling
A.method, since the type given tosuperis excluded from the search. I would consider this usage ofsuperflaky to say the least, since it will skip a member of the inheritance hierarchy (seemingly haphhazardly), which is inconsistent with what I would expect as a developer. Since users ofsuperare already encouraged to maintain consistency, I'd recommend against this practice.
