💼 Career

Knowing how to create and manage lists is essential for organizing data in many programming jobs.

1

Create the initial guest list

Create a list called guests with these exact names: 'Alice', 'Bob', and 'Charlie'.

Python

# Create the list guests with 'Alice', 'Bob', and 'Charlie'
guests = []  # Your code here

Need a hint?

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

2

Add a new guest to the list

Add the guest name 'Diana' to the existing guests list using the append() method.

Python

guests = ['Alice', 'Bob', 'Charlie']
# Add 'Diana' to the guests list
# Your code here

Need a hint?

Use guests.append('Diana') to add the new guest.

3

Prepare to display the guest list

Create a variable called guest_list_str that joins all names in guests into a single string separated by commas and spaces.

Python

guests = ['Alice', 'Bob', 'Charlie']
guests.append('Diana')
# Join the guest names into one string separated by ', '
guest_list_str = ''  # Your code here

Need a hint?

Use ', '.join(guests) to combine list items into a string.

4

Display the full guest list

Print the string guest_list_str to show all guest names separated by commas.

Python

guests = ['Alice', 'Bob', 'Charlie']
guests.append('Diana')
guest_list_str = ', '.join(guests)
# Print the guest_list_str
# Your code here

Need a hint?

Use print(guest_list_str) to display the names.
