Method parsing Order (MRO) for Python

MRO is the method resolution order, which is used primarily to determine the path of a property that is tuned at multiple inheritance (from which class).

Do you really understand the MRO algorithm in Python?

Api:

1 classtype (object):2     """3 type (object), the object ' s type4 type (name, bases, Dict), a new type5     """6     defMRO (self):#real signature unknown; restored from __doc__7         """8 MRO () List9 return a type ' s method resolution orderTen         """ One         return[]

Test code:

1 #!/usr/bin/env python2 classA (object):3     def __init__(self):4         Print "Enter A"5         Print("Leave A")6 7 8 classB (object):9     def __init__(self):Ten         Print "Enter B" One         Print "Leave B" A  -  - classC (A, b): the     def __init__(self): -         Print "Enter C" -Super (C, self).__init__() -         Print "Leave C" +  -b =C () +Mo = B.__class__. MRO () A PrintMo

Output:

Enter C
Enter A
Leave A
Leave C
[<class ' __main__. C ';, <class ' __main__. A ';, <class ' __main__. B ';, <type ' object ';]
