Answer Key

Tuples – Operations
Section A: Quick Questions
Q1
A — A set of named constants
Q2
A — Prevents typos and invalid values
Q3
A — The value assigned to RED (e.g., 1)
Q4
B — 'RED' (the name as a string)
Q5
B — Yes Color.RED == Color.RED is True
Section B: Match the Pairs
Q1
from Enum import enum → Error: Incorrect import — use from enum import Enum
Q2
Color(RED) → Error: Access members with Color.RED
Q3
from enum import Enum → Valid: Correct import for Enum class
Q4
Color.RED.value → Ok: Access the numeric value of an enum member
Q5
list(range(3)) → Output: [0, 1, 2]
Q6
type(True) → Output: <class 'bool'>
Section C: Definitions
Q1
Enum — A class for creating sets of named constants.~~Member
Section D: Fill in the Blanks
Q1
from enum import Enum class Color(Enum): RED = 1
Q2
class Color(Enum): RED = 1
Q3
print(Color.RED.value)
Q4
print(Color.RED.name)
Q5
for c in Color: print(c)
Section E: Spot the Error
Q1
A — Must import Enum first: from enum import Enum
Q2
E — Duplicate values create aliases, not new members. Use unique values.
Q3
F — Cannot reassign enum members they are immutable
Q4
D — Convention: enum member names should be UPPER_CASE
Q5
F — Compare with Color.RED, not the string 'RED'
