1

What is a tuple in Python primarily?

a

A set of key-value pairs

b

A mutable sequence

c

A mutable unordered collection

d

An immutable ordered collection

2

How do you create a single-element tuple?

a

Use {element}

b

Use (element,)

c

Use (element)

d

Use [element]

3

Are tuples mutable or immutable?

a

Immutable

b

Depends on elements

c

Partially mutable

d

Mutable

4

How can you concatenate two tuples t1 and t2?

a

Using the extend() method

b

Using the * operator

c

Using the + operator

d

Using the append() method

5

How do you convert a list to a tuple?

a

convert(my_list)

b

list(my_tuple)

c

tuple(my_list)

d

my_tuple.to_tuple()

6

What does len(my_tuple) return?

a

The memory size of the tuple

b

The maximum element value

c

Number of elements in the tuple

d

Whether the tuple is mutable

7

Can a tuple contain mutable objects like a list inside?

a

No

b

Yes

c

Only if the inner object is also immutable

d

Only in Python 3.9+

8

How do you unpack a 3-tuple t into variables a, b, c?

a

t = (a, b, c)

b

a, b, c = t

c

a = t[0]; b = t[1]; c = t[2]

d

a, b, c = tuple(t)

9

What is the result of (1,2,3) * 2?

a

(2, 3, 4)

b

(1, 2, 3, 1, 2, 3)

c

(2, 4, 6)

d

(1, 2, 3, 2)

10

Can a tuple be used as a dictionary key?

a

Only in Python 2

b

Yes, if all elements are hashable

c

Only if it contains strings

d

No, never

Feedback

1

Tuples are ordered like lists but immutable.

2

A trailing comma distinguishes a 1-tuple from a plain expression.

3

Tuples cannot be changed after creation.

4

The + operator returns a new tuple with elements from both.

5

The built-in tuple() casts an iterable to a tuple.

6

len returns the count of elements in the tuple.

7

Tuples can contain mutable elements; immutability is about the tuple itself.

8

Tuple unpacking assigns each element to a variable.

9

Tuple repetition duplicates the sequence.

10

Hashable tuples (with hashable contents) can be dict keys.

You can integrate the game into an LMS compatible with LTI 1.1 or LTI 1.3 such as Canvas, Moodle, or Blackboard. This way, the scores will be automatically saved into the platform’s gradebook.
