Fix the inheritance network
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(), I need to draw the complete inheritance network for H. Also, i need to indicate the order in which all its classes are searched for attributes.
below is the picture I drew:
I am not sure if I drew the order correct. can someone help me to fix it?

type.mro() will give you the order:
>>> type.mro(H)
[__main__.H,
__main__.E,
__main__.F,
__main__.C,
__main__.D,
__main__.A,
__main__.G,
__main__.B,
object]
As you can see you have a number of errors in your numbering.
If you need the hierarchy then you can use 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))]]]]
