Question 1

Which line of code will change the starting_dictionary to the final_dictionary?

starting_dictionary = {
    "a": 9,
    "b": 8,
}

final_dictionary = {
    "a": 9,
    "b": 8,
    "c": 7,
}

final_dictionary = starting_dictionary.append({"c": 7})

final_dictionary = starting_dictionary += {"c": 7}

final_dictionary = starting_dictionary["c"]: 7

final_dictionary = starting_dictionary["c"] = 7

starting_dictionary["c"] = 7
final_dictionary = starting_dictionary

Correct Answer

starting_dictionary["c"] = 7
final_dictionary = starting_dictionary

Explanation

Correct! Well done!

Question 2

Which line of code will produce an error?

dict = {
    "a": 1,
    "b": 2,
    "c": 3,
}

dict["c"] = [1, 2, 3]

for key in dict:
    dict[key] += 1

dict[1] = 4

print(dict[1])

Correct Answer

print(dict[1])

Explanation

There is no key that matches 1, this will give you a KeyError.

Question 3

Which line of code will print "Steak"?

order = {
    "starter": {1: "Salad", 2: "Soup"},
    "main": {1: ["Burger", "Fries"], 2: ["Steak"]},
    "dessert": {1: ["Ice Cream"], 2: []},
}

print(order["main"][2])

print(order["dessert" - 1][2][0])

print(order[main][2][0])

print(order["main"][2][0])

Correct Answer

print(order["main"][2][0])

Explanation

[2] accesses the value with key 2, [0] gets the first item from the list.
