What is a potential issue with using multiple inheritance?
Difficulty in determining method resolution order
Inability to define class attributes
Naming conflicts in class methods
Automatic resolution of method conflicts
Answer: Option
Explanation:
Multiple inheritance in Python may lead to the diamond problem, resulting in difficulty determining the method resolution order and potential ambiguity.
15.
In Python, what happens when a subclass defines a method with the same name as a method in its superclass?
The superclass method is automatically overridden
The subclass method is ignored
An error occurs, and the program crashes
