Tuple immutability in Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a tuple named my_tuple with values 1, 2, and 3.

Python

my_tuple = ([1])

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

A[1, 2, 3]

B{1, 2, 3}

C1, 2, 3

D"1, 2, 3"

💡 Hint

Common Mistakes

Using square brackets instead of parentheses creates a list, not a tuple.

Using curly braces creates a set, not a tuple.

Putting values inside quotes creates a string, not a tuple.

Tuples are created using parentheses with comma-separated values. So (1, 2, 3) creates a tuple.

2fill in blank

medium

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

Python

second_element = my_tuple[[1]]

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

💡 Hint

Common Mistakes

Using index 2 to get the second element (actually the third).

Using index 0 to get the second element (actually the first).

Tuple elements start at index 0, so the second element is at index 1.

Fix the error in the code that tries to change the first element of the tuple my_tuple to 10.

Python

my_tuple[[1]] = 10

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

💡 Hint

Common Mistakes

Trying to assign a value to a tuple index causes a TypeError.

Thinking negative indices allow assignment in tuples.

Tuples are immutable, so you cannot assign a new value to any index. This code will cause an error no matter the index.

The fix is to create a new tuple instead of changing an element.

4fill in blank

hard

Fill both blanks to create a new tuple new_tuple by replacing the first element of my_tuple with 10.

Python

new_tuple = ([1],) + my_tuple[[2]:]

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

💡 Hint

Common Mistakes

Forgetting the comma after 10, which makes it an int, not a tuple.

Using the wrong slice index, which includes the first element.

We create a new tuple starting with 10, then add all elements of my_tuple from index 1 onward (skipping the first element at index 0).

5fill in blank

hard

Fill all three blanks to create a tuple filtered_tuple with only elements greater than 2 from my_tuple.

Python

filtered_tuple = tuple(x for x in my_tuple if x [1] [2])
result = filtered_tuple[[3]]

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

C0

D<

💡 Hint

Common Mistakes

Using the less than operator instead of greater than.

Using the wrong index to access the first element.

This code filters elements greater than 2 and then gets the first element (index 0) of the filtered tuple.
