🐍 Python Data Structures Quiz

Test your knowledge of Python data structures, methods, and operations!

Question 1:

What will be the output of the following code? my_list = [1, 2, 3, 4] my_list.append([5, 6]) print(len(my_list))
A. 4
B. 5
C. 6
D. Error

Question 2:

Which operation is not valid for Python sets?
A. set1.intersection(set2)
B. set1[0]
C. set1.add(element)
D. set1.update(set2)

Question 3:

What will this code return? dict1 = {'a': 1, 'b': 2} dict2 = {'b': 3, 'c': 4} dict1.update(dict2) print(dict1['b'])
A. 2
B. 3
C. None
D. KeyError

Question 4:

What's the difference between a tuple and a list in Python?
A. Tuples use parentheses instead of square brackets
B. Tuples are immutable while lists are mutable
C. Tuples can only contain numbers
D. Lists are faster than tuples

Question 5:

What will this code output? my_dict = {'a': 1, 'b': 2} print(my_dict.get('c', 0))
A. None
B. 0
C. KeyError
D. False

Question 6:

Complete the code to create a set from a list and remove duplicates: my_list = [1, 2, 2, 3, 3, 4] unique_items = _____(my_list)

Hint: Use a built-in function that converts an iterable to a set

Question 7:

Complete the list comprehension to square even numbers: [x**2 for x in range(10) _____ x % 2 == 0]

Hint: We need a conditional statement in the list comprehension

Question 8:

Add a key-value pair to a dictionary: my_dict = {} my_dict_____ = 'value'

Hint: Use square brackets with the key name

Question 9:

Convert a dictionary's keys to a list: my_dict = {'a': 1, 'b': 2} keys = list(my_dict._____())

Hint: Use the method that returns a view of dictionary keys

Question 10:

Join list elements into a string: my_list = ['Hello', 'World'] result = ' '._____(my_list)

Hint: Use the string method that concatenates iterable elements
