Tuple vs list comparison in Python - Interactive Practice

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:

💡 Hint

Common Mistakes

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

Using curly braces {} which create a set or dictionary.

Putting the number inside quotes which makes it a string.

The tuple elements are separated by commas and enclosed in parentheses. The third element should be the integer 3.

medium

Complete the code to compare if a tuple and a list with the same elements are equal.

Python

result = (1, 2, 3) [1] [1, 2, 3]

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

A>

B!=

C<

D==

💡 Hint

Common Mistakes

Using != which checks for inequality.

Using < or > which compare order but are not suitable here.

Using == compares the values and order of elements. A tuple and a list with the same elements in the same order are not equal because they are different types.

3fill in blank

hard

Fix the error in the code to convert a list to a tuple.

Python

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

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

Bdict

Cset

Dlist

💡 Hint

Common Mistakes

Using list() which returns a list, not a tuple.

Using set() which creates a set, not a tuple.

Using dict() which creates a dictionary, not a tuple.

The tuple() function converts an iterable like a list into a tuple.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps each index to its tuple element.

Python

my_tuple = (10, 20, 30)
index_map = [1]: [2] for [1], [2] in enumerate(my_tuple)

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

Avalue

Bindex

Ckey

Ditem

💡 Hint

Common Mistakes

Swapping key and value in the dictionary comprehension.

Using variable names not matching the unpacking from enumerate.

In the comprehension, 'index' is the dictionary key and 'value' is the tuple element.

5fill in blank

hard

Fill all three blanks to create a list of tuples from a list of lists.

Python

list_of_lists = [[1, 'a'], [2, 'b'], [3, 'c']]
list_of_tuples = [([1], [2]) for [3] in list_of_lists]

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

Aitem[0]

Bitem[1]

Citem

Delement

💡 Hint

Common Mistakes

Using wrong variable names in the comprehension.

Not accessing elements by index correctly.

We unpack each 'item' from the list_of_lists and create a tuple with its first and second elements.
