Why tuples are used in Python - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a tuple with three elements.

Python

my_tuple = (1, 2, [1])

Drag options to blanks, or click blank then click option'

A3

B[3]

C{3}

D"3"

Attempts:

3 left

💡 Hint

Common Mistakes

Using square brackets [] which create a list instead of a tuple.

Using curly braces {} which create a set instead of a tuple.

Putting the number 3 inside quotes which makes it a string.

The tuple elements are separated by commas inside parentheses. The element 3 is added as a number, not as a list, set, or string.

2fill in blank

medium

Complete the code to access the second element of the tuple.

Python

second_element = my_tuple[1]

Drag options to blanks, or click blank then click option'

A[1]

B(1)

C{1}

D<1>

Attempts:

3 left

💡 Hint

Common Mistakes

Using parentheses () which is for tuples, not indexing.

Using curly braces {} which are for sets or dictionaries.

Using angle brackets <> which are not valid syntax.

Tuples are accessed by index using square brackets []. The second element is at index 1 because counting starts at 0.

3fill in blank

hard

Complete the code to attempt to modify the first element of the tuple, demonstrating its immutability by causing an error.

Python

my_tuple = (1, 2, 3)
my_tuple[1] = 4

Drag options to blanks, or click blank then click option'

A.append(4)

B[0]

C(0)

D[1]

Attempts:

3 left

💡 Hint

Common Mistakes

Using .append(4) which causes a syntax error instead of demonstrating immutability.

Using parentheses (0) which is invalid syntax.

Using [1] which also errors but targets the wrong element.

Tuples are immutable, so you cannot change elements by index. my_tuple[0] = 4 raises TypeError: 'tuple' object does not support item assignment, demonstrating immutability.

4fill in blank

hard

Fill both blanks to create a tuple and check its type.

Python

data = [1](1, 2, 3)
type_of_data = type(data) == [2]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using list() instead of tuple() to create the data.

Comparing type to list or dict instead of tuple.

Using incorrect syntax for type comparison.

The tuple() function creates a tuple from the given elements. The type() function returns the type, which is compared to tuple to check if the data is a tuple.

5fill in blank

hard

Fill all three blanks to create a tuple, access an element, and check immutability.

Python

my_tuple = ([1], [2], [3])
value = my_tuple[1]
try:
    my_tuple[1] = 10
except TypeError:
    error = True

Drag options to blanks, or click blank then click option'

B20

C30

D40

💡 Hint

Common Mistakes

Using lists or other data types instead of numbers.

Trying to assign a new value to a tuple element without error handling.

Confusing tuple immutability with list mutability.

The tuple is created with three numbers 10, 20, and 30. Accessing the second element (index 1) gives 20. Trying to assign a new value to a tuple element raises a TypeError because tuples are immutable.
