Data Types - Dictionary

Question 1

Can Dictionaries be sliced, and why?

Answer 1

No - Python is simply not programmed to support it

Question 2

person = {“name”: “Alice”, “age”: 30}

Give 2 ways to remove “age” from this dictionary

Answer 2

del person[“age”]

person.pop(“age”)

.remove() is a method of List

Question 3

scores = {“Alice”: 90, “Bob”: 75, “Clara”: 88}

Loop through “scores” and print “High score” if score is >= 80

Answer 3

for score in scores.values():
if score >= 80:
print(“High score”)

.values() is a method of Dictionaries which produces an “iterator-like view object” which can be looped through.

Output syntax:
dict_values([value1, value2, value3])

Question 4

What is .values()

Answer 4

.values() is a method of Dictionaries which produces an “iterator-like view object” which can be looped through.

Output syntax:
dict_values([value1, value2, value3])

Question 5

scores = {“Alice”: 90, “Bob”: 75, “Clara”: 88}

Convert the above to a List, only containing the “scores”(values)

Answer 5

score_list = list(scores.values())
