修复继承网络

Question

class A : pass
class B : pass
class C(A) : pass
class D(A,B) : pass
class E(A) : pass
class F(C,D) : pass
class G(B) : pass
class H(E,F,G) : pass

o = H（），我需要为H绘制完整的继承网络。另外，我需要指出搜索所有类的属性的顺序。

下面是我画的图片：

我不确定我的订单是否正确。有人可以帮我修理吗？

Answer 1

type.mro()会给您订单：

>>> type.mro(H)
[__main__.H,
 __main__.E,
 __main__.F,
 __main__.C,
 __main__.D,
 __main__.A,
 __main__.G,
 __main__.B,
 object]

正如您所看到的，您的编号中存在许多错误 如果您需要层次结构，则可以使用inspect：

>>> import inspect
>>> inspect.getclasstree(inspect.getmro(H))
[(object, ()),
 [(__main__.A, (object,)),
  [(__main__.C, (__main__.A,)),
   [(__main__.F, (__main__.C, __main__.D)),
    [(__main__.H, (__main__.E, __main__.F, __main__.G))]],
   (__main__.D, (__main__.A, __main__.B)),
   [(__main__.F, (__main__.C, __main__.D)),
    [(__main__.H, (__main__.E, __main__.F, __main__.G))]],
   (__main__.E, (__main__.A,)),
   [(__main__.H, (__main__.E, __main__.F, __main__.G))]],
  (__main__.B, (object,)),
  [(__main__.D, (__main__.A, __main__.B)),
   [(__main__.F, (__main__.C, __main__.D)),
    [(__main__.H, (__main__.E, __main__.F, __main__.G))]],
   (__main__.G, (__main__.B,)),
   [(__main__.H, (__main__.E, __main__.F, __main__.G))]]]]
