Which of these data types does Python not natively support?

• Lists

• Tuples

• Arrays

• Dictionaries

What is the output of the following code snippet:
print(type("Hello, World!"))

• <class 'str'>

• <class 'int'>

• <class 'list'>

• <class 'list'>

What will be the output of the following pseudocode?
Initialize x as 10;
If x is of type int,
print "Integer"
else
print "Not Integer"

• Integer

• Not Integer

• Error

• None

Evaluate this pseudocode:
Set x = [1, 2, 3];
If x is a list, print length of x, else print "Not a list"

• 3

• 0

• 1

• 2

What is the default type of data returned by the input() function in Python 3.x?

• int

• string

• boolean

Find the mistake:
user_input = input("Enter a number: ");
print("You entered: ", int(user_input))

• Syntax error

• No error

• int() should be str()

• input() function used incorrectly

How is memory allocation for lists and tuples different in Python?

• Lists use more memory than tuples

• Tuples use more memory than lists

• Both use the same amount of memory

• Memory usage is random and unpredictable

Given a class Animal and a subclass Dog, which method demonstrates polymorphism?

• Animal.speak() and Dog.speak() have different implementations

• Dog has the same attributes as Animal

• Dog uses a method from Animal without changing it

• Animal has a method not present in Dog

Pseudocode:
Create a base class 'Shape', derived classes 'Circle', 'Square'; Implement method 'area' in both

• Error, as 'area' cannot be implemented in 'Shape'

• Circle' and 'Square' can't inherit from 'Shape'

• area' method behaves differently in 'Circle' and 'Square'

• 'Shape' should not have an 'area' method
