1.Why is isinstance() useful?
isinstance() is useful for performing type checking. It helps ensure that an object is of the expected type before performing certain operations. This is especially important in scenarios involving inheritance and polymorphism.
2.What does isinstance(object, (Class1, Class2)) do?
This checks if object is an instance of either Class1 or Class2. If object is an instance of either class, it returns True; otherwise, it returns False.
3.What will isinstance(None, object) return?
It will return True. This is because None is an instance of the base class object.
4.Can isinstance() be used for built-in types like integers and strings?
Yes, isinstance() can be used to check the type of built-in types as well as custom-defined classes.
5.Can you use isinstance() to check if an object belongs to a module?
No, isinstance() is not used to check if an object belongs to a module. You can use isinstance() to check if an object belongs to a specific class or its subclasses.
