Question 1 of 31

Select the true statement about composition.

Composition extends a class’s capabilities by adding new components and modifying the existing ones

Composition allows a class to be projected as a container of different classes

Composition is a concept that promotes code reusability, while Inheritance promotes encapsulation

Composition is based on the has a relation, so it cannot be used together with inheritance

Correct Answer: B

Composition allows a class to be projected as a container of different classes. This is because composition involves building complex types by combining objects of other types, establishing a 'has-a' relationship. It promotes flexibility and modular code design since the container class can access the public interface of the contained classes, but not their internal details.

Question 2 of 31

Analyze the following snippet and select the statement that best describes it.

The code is an example of implicitly chained exceptions.

The code is erroneous as the OwnMath class does not inherit from any Exception type class

The code is fine and the script execution is not interrupted by any exception.

The code is an example of explicitly chained exceptions

Correct Answer: B

The code is erroneous because the OwnMath class does not inherit from any Exception type class. In Python, exceptions must be derived from BaseException or its subclasses. Attempting to use a class that does not inherit from an exception base class as an exception will result in a TypeError. Therefore, the provided class definition for OwnMath is incorrect for exception handling purposes.

Question 3 of 31

Analyze the following snippet and select the statement that best describes it.

self.name is the name of a class variable

var1 is the name of a global variable

Excalibur is the value passed to an instance variable

weapon is the value passed to an instance variable

Correct Answer: C

The given code snippet defines a class named Sword. Within this class, 'var1' is set as a class variable with the value 'weapon'. The initializer method '__init__' defines 'self.name' as an instance variable and assigns it the value 'Excalibur'. So, 'Excalibur' is the value assigned to an instance variable when an object of the class Sword is created.

Question 4 of 31

The following snippet represents one of the OOP pillars. Which one is that?

Serialization

Inheritance

Encapsulation

Polymorphism

Correct Answer: D

The snippet shows different classes where some have a method named 'run'. Despite the presence of the 'fly' method in class B, the attempt to execute 'run' on all instances showcases the concept of polymorphism. Polymorphism allows objects of different classes to be treated as objects of a common superclass. It facilitates the execution of the same method (or interface) in different ways for various object instances. In this example, the intention is to invoke the 'run' method polymorphically, although it would encounter an error due to the 'fly' method in class B.

Question 5 of 31

Analyze the following function and choose the statement that best describes it.

It is an example of a decorator that accepts its own arguments.

It is an example of decorator stacking.

It is an example of a decorator that can trigger an infinite recursion

The function is erroneous.

Correct Answer: D

The function presented is erroneous. The code references a variable 'our_function' which is not defined anywhere within the scope of the function. Additionally, there is a missing colon in line 3. These issues would result in a NameError when the code is executed, thus making the function incorrect as written. To correct this, ensuring that the referenced function names are consistent and properly defined is necessary.
