Let’s start out on this highly detailed page on handling lists:
Create an empty list:
friends = 
Populate a list:
friends = ['bill', 'jeff', 'jim'] for friend in friends: print("Hello, " + friend.title() + "!")
A list in Python is defined inside square brackets.
Access an item using its index:
Remember these are 0-based arrays. The index goes inside square brackets:
friend = friends print(friend.title())
usernames = ['bernice', 'cody', 'aaron'] user_count = len(usernames) print(user_count)
You don’t need to know how many items are in the list in order to get the last item; you use a negative number:
friend = friends[-1] print(friend.title())
Iterate through all items on a list:
for friend in friends: print(friend.title())
- Continue editing examples.py.
- Define a list. It can be your friends, your pets, your deadliest enemies.
- Print the first item from the list.
- Print the third item.
- Print all the elements of the list.
