How do I check the MRO in Python?

How do I check the MRO in Python?

You can check the Method Resolution Order (MRO) in Python using the __mro__ attribute or the mro() method of a class.

Can you show me an example?

Sure! Here's a simple example:

class A:
    pass

class B(A):
    pass

class C(A):
    pass

class D(B, C):
    pass

print(D.__mro__)

This will output the MRO for class D.

What does the output mean?

The output shows the order in which Python will look for methods in the class hierarchy. It lists the classes in the order they will be searched.

Is there a way to visualize the MRO?

Yes! You can use tools like pyreverse from the pylint package to visualize class hierarchies, including MRO.
