mro sourcing

Python advanced-MRO and super in succession Write in front If not specifically stated, the following are based on Python3 SummaryThis article describes Python how an inheritance relationship can be super() returned by calling the "parent class" method, super(Type, CurrentClass) returning the proxy for the CurrentClass MRO Type next class, and how to design the Python class for proper initializatio

Mro Method resolution order is used by python to parse the method call sequence. Mro is important for method calling in Multi-inheritance. There is a built-in function in Python that is closely related to Mro-Super. As the name suggests, super should look like a method to call the parent class, which is usually the same. Let's look at a piece of code: Class A (ob

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).http://blog.csdn.net/imzoer/article/details/8737642Do 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

MRO is the method Resolution order, which is proposed mainly to solve the python in multiple inheritance, when the parent class has the same name function, the ambiguity of the problemLet's look at an example below: import Inspect class D: pass class C (D): pass class B (D): pass class A (B, C): pass if __name__ = = " __main__ " : print (Inspect.getmro (A)) b and C inherit d a inherit B and c This is a simple multiple inhe

Foo and bar methods on its own.Then, follow the principle of depth first, from left to right.For the Foo method:Find yourself first, I did not implement Foo, and then look up c_2, c_2 also did not implement Foo, continue to find C_1,c_1 also did not implement Foo, continue to find p_1,p_1 implementation of the Foo method.Then the output of C_3.foo () is: called P1-foo ()For the Bar Method:Find yourself first, do not have bar, and then look up c_1,c_1 did not implement bar, continue to find P_1,

Recently, I checked the event sourcing mode and found that it is quite consistent with my potential goals. In software development, objects usually perform logical operations in the memory, and then the final state of objects is persisted to the database. If,CodeIf an execution error occurs, we can only reverse the error based on the final result. However, the general result is that we cannot find out why this happens, especially in high concurrency!
