What are some examples of multiple inheritance in Python?

Multiple inheritance in Python allows a class to inherit from more than one base class. For example, consider the following code:

class A:
    def method_a(self):
        return 'Method A'

class B:
    def method_b(self):
        return 'Method B'

class C(A, B):
    pass

c = C()
print(c.method_a())  # Output: Method A
print(c.method_b())  # Output: Method B

Can you explain how the method resolution order (MRO) works in this context?

Sure! In Python, the method resolution order (MRO) determines the order in which base classes are searched when calling a method. You can view the MRO of a class using the __mro__ attribute or the mro() method. For example:

print(C.__mro__)
# Output: (<class '__main__.C'>, <class '__main__.A'>, <class '__main__.B'>, <class 'object'>)

What are some potential issues with multiple inheritance?

Some potential issues include the diamond problem, where a class inherits from two classes that have a common base class, leading to ambiguity. This can complicate the MRO and make the code harder to understand.
