Understanding Inheritance in Python

What is inheritance in Python?

• Inheritance is a mechanism in Python where a class can derive properties and behaviors from another class.

• Inheritance is a way to create multiple classes in Python.

• Inheritance allows a class to inherit only methods, not properties.

• Inheritance is a method to delete properties from a class.

Which keyword is used to define a base class in Python?

• classify

• base

• class

• define

What is the purpose of the 'super()' function in inheritance?

• To delete methods from a parent class.

• To create a new class in inheritance.

• To override methods in the child class.

• The purpose of 'super()' is to call methods from a parent class in inheritance.

Can a derived class override methods of a base class?

• A derived class can only inherit methods, not override them.

• Only static methods can be overridden by a derived class.

• No, a derived class cannot override methods of a base class.

• Yes, a derived class can override methods of a base class.

What is multiple inheritance in Python?

• Multiple inheritance is a method to create multiple instances of a class.

• Multiple inheritance is a feature that prevents code reuse in Python.

• Multiple inheritance allows a class to inherit from a single parent class.

• Multiple inheritance is a feature in Python where a class can inherit from multiple parent classes.

How do you call a method from a base class in a derived class?

• Use 'BaseClassName::MethodName()' or 'super.MethodName()'.

• Call MethodName() directly

• Use MethodName() from the derived class

• Invoke BaseClassName.MethodName()

What is the difference between single and multiple inheritance?

• Single inheritance can involve multiple child classes.

• Single inheritance allows for multiple parent classes.

• Single inheritance involves one parent class, while multiple inheritance involves multiple parent classes.

• Multiple inheritance is only possible in certain programming languages.

What happens if a derived class does not implement a method from the base class?

• The method is automatically deleted from the base class.

• The derived class must always override the method.

• The derived class will throw an error at runtime.

• The derived class inherits the method or must implement it if it's abstract.

Can a class inherit from multiple classes in Python?

• No, a class can only inherit from one class in Python.

• No, Python does not support multiple inheritance.

• Yes, but only if the classes are in the same module.

• Yes, a class can inherit from multiple classes in Python.

What is the method resolution order (MRO) in Python?

• The MRO is the order of execution for Python scripts.

• The method resolution order (MRO) is the order in which Python looks for methods in a hierarchy of classes.

• The MRO is a built-in function that returns class attributes.

• The MRO defines the syntax rules for Python programming.
