reversed() function in Python - Mini Project: Build & Apply

Using the reversed() Function in Python

📖 Scenario: You are organizing a list of guests for a party. You want to see the list in reverse order to plan the seating arrangement from the last guest to the first.

🎯 Goal: Learn how to use the reversed() function to reverse the order of items in a list and display the reversed list.

📋 What You'll Learn

Create a list of guest names with exact values

Use a variable to hold the reversed list

Use the reversed() function to reverse the list

Print the reversed list

💡 Why This Matters

🌍 Real World

Reversing lists is useful when you want to process items from the end to the start, like undoing actions or showing recent items first.

💼 Career

Understanding how to reverse data helps in data processing, user interface design, and algorithms where order matters.

1

Create the guest list

Create a list called guests with these exact names in order: 'Alice', 'Bob', 'Charlie', 'Diana', 'Ethan'.

Python

# Create the guest list
# Your code here

Need a hint?

Use square brackets [] to create a list and separate names with commas.

2

Create a variable for the reversed list

Create a variable called reversed_guests and set it to the result of reversed(guests).

Python

guests = ['Alice', 'Bob', 'Charlie', 'Diana', 'Ethan']
# Create reversed_guests using reversed(guests)
# Your code here

Need a hint?

The reversed() function returns an iterator. Assign it to a variable.

3

Convert reversed iterator to a list

Convert reversed_guests to a list and assign it back to reversed_guests using list().

Python

guests = ['Alice', 'Bob', 'Charlie', 'Diana', 'Ethan']
reversed_guests = reversed(guests)
# Convert reversed_guests to a list
# Your code here

Need a hint?

Use list() to turn the reversed iterator into a list you can print.

4

Print the reversed guest list

Print the variable reversed_guests to display the reversed list of guests.

Python

guests = ['Alice', 'Bob', 'Charlie', 'Diana', 'Ethan']
reversed_guests = reversed(guests)
reversed_guests = list(reversed_guests)
# Print reversed_guests
# Your code here

Need a hint?

Use print() to show the reversed list on the screen.
