Question 1

Diamond Problem. Suppose you have the following class hierarchy:

class A:

def hello(self):

print('Hello from class A')

class B(A):

def hello(self):

print('Hello from class B')

class C(A):

def hello(self):

print('Hello from class C')

class D(A, C):

pass

What is the result of the following method call?

D().hello()

A : This code will raise the TypeError exception because Python cannot create a consistent method resolution order (MRO) for bases A, C.

B : Hello from class C

C : Hello from class A

D : Hello from class B

Answer: A

Question 2

Which of the following statements best describes the difference between inheritance and composition in object-oriented programming?

A : Inheritance is a concept used in procedural programming, while composition is specific to object-oriented programming.

B : Inheritance allows a class to inherit properties and methods from another class, while composition enables objects to contain other objects.

C : Inheritance and composition are two different terms used interchangeably to describe the same concept.

D : Inheritance allows an object to contain other objects, while composition enables a class to inherit properties and methods from another class.

Answer: B

Question 3

In Python, which of the following methods is necessary to override when inheriting from a built-in immutable class (like tuple or str) if you want to add additional attributes to it?

A : __new__()

B : __str__()

C : __init__()

D : __call__()

Answer: A

Question 4

You are building a Python application that needs to send an HTTP POST request with JSON data to a remote server. Which code snippet correctly demonstrates the usage of the requests module to accomplish this task?

A : import requests

url = "https://api.example.com/data"

data = {"key": "value"}

response = requests.get(url, json=data)

B : import requests

url = "https://api.example.com/data"

data = {"key": "value"}

response = requests.patch(url, json=data)

C : import requests

url = "https://api.example.com/data"

data = {"key": "value"}

response = requests.put(url, json=data)

D : import requests

url = "https://api.example.com/data"

data = {"key": "value"}

response = requests.post(url, json=data)

Answer: D

Question 5

Suppose you have the following code:

class ClientList(list):

def search_email(self, value):

result = [client for client in self if value in client.email]

return result

class Client:

all_clients = ClientList()

def __init__(self, name, email):

self.name = name

self.email = email

Client.all_clients.append(self)

Select all true statements. (select 2)

A :

all_clients attribute is an example of an instance attribute of Client class.

B : all_clients is a class attribute of Client class.

C : name and email attributes are examples of instance attributes of Client class.

D : search_email attribute is an example of an instance attribute of ClientList class.
