Enumerations – Practical Use

Enum members are used as meaningful, type-safe constants instead of raw strings or numbers

What it does: + creates a new tuple containing all items from both tuples. count() is one of the few methods tuples support. Adding two tuples joins them into a new tuple - the result keeps the tuple type. Multiplying repeats the whole tuple - 3 copies of (1,2) joined together. count() tells you how many times a value appears - 2 appears twice in this tuple. index() returns the position (index), not the value - 20 is at position 1. Tuples are minimal - only count() and index() because they can't be changed. sorted() always returns a list even when you pass it a tuple.

Common mistakes: Tuples don't have sort(). Use sorted() and convert back. Must concatenate with a tuple: (4,) not just 4.

Quick Questions

1. (1,2) + (3,4) returns?

A. (1, 2, 3, 4) ✓

B. [1, 2, 3, 4]

Adding two tuples joins them into a new tuple - the result keeps the tuple type

2. (1,2) * 3 returns?

A. (3, 6)

B. (1, 2, 1, 2, 1, 2) ✓

Multiplying repeats the whole tuple - 3 copies of (1,2) joined together

3. t = (1,2,2,3)\nt.count(2) returns?

A. 2 ✓

B. 1

count() tells you how many times a value appears - 2 appears twice in this tuple

4. t = (10,20,30)\nt.index(20) returns?

A. 20

B. 1 ✓

index() returns the position (index), not the value - 20 is at position 1

5. How many methods do tuples have?

A. Just 2: count() and index() ✓

B. Many like lists

Tuples are minimal - only count() and index() because they can't be changed

Match the Pairs

t.append(4) → Error: Tuples have no append method

t.remove(1) → Error: Tuples are immutable — no remove method

(1, 2) + (3, 4) → Valid: Concatenate two tuples into one

t.count(2) → Ok: Count how many times 2 appears in t

(1, 2) * 2 → Output: (1, 2, 1, 2)

sorted((3, 1, 2)) → Output: [1, 2, 3]

Key Term

Concatenation (+)

Combines two tuples into a new tuple.~~Repetition (*)

Fill in the Blanks

1. t = (1, 2) + (3, 4)

2. t = (1, 2) * 3

3. t = (1, 2, 2, 3) print(t.count(2))

4. t = (10, 20, 30) print(t.index(20))

5. t = (3, 1, 2) print(sorted(t))

Spot the Error

Question 1

A t = (3, 1, 2)

B t.sort()

C print('Sorted:', t)

D print('Done')

Line B — Tuples don't have sort(). Use sorted() and convert back.

Question 2

A t = (1, 2, 3)

B t += 4

C print('Tuple:', t)

D print('Done')

Line B — Must concatenate with a tuple: (4,) not just 4

Question 3

A t = (1, 2, 3)

B idx = t.index(5)

C print('Index:', idx)

D print('Done')

Line B — index() raises ValueError if value isn't in the tuple

Question 4

A t = (3, 1, 2)

B result = sorted(t)

C print('Sorted:', result)

D # expects tuple

Line B — sorted() returns a list. Wrap in tuple() to get a tuple back.

Question 5

A t = (1, 2) + [3, 4]

B label = 'Combined'

C print('Combined:', t)

D print('Done')

Line A — Can't concatenate tuple + list. Both must be the same type.
