A list is like a shopping list you make when you go shopping.

Create a list. The count starts from zero.

>>> fruits = [ "bannanas", "coconuts", "pineapple"]

Print the first element (first entry) in the list.

>>> print(fruits[0])
bannanas

Print the second element in the list.

>>> print(fruits[1])
coconuts

Change the value of an element in the list. Here we change the second item in the list from coconuts to melons.

>>> fruits[1] = "melons"
>>> print(fruits)
['bannanas', 'melons', 'pineapple']

Print the number of items in our list.

>>> length = len(fruits)
>>> print(length)
3

Add another item to the list.

>>> fruits.append("figs")
>>> print(fruits)
['bannanas', 'melons', 'pineapple', 'figs']

Insert another item into the list in a specific place.

>>> fruits.insert(2, "coconuts")
>>> print(fruits)
['bannanas', 'melons', 'coconuts', 'pineapple', 'figs']

Print the index number of the item.

>>> mybestfruit = fruits.index("melons")
>>> print(mybestfruit)
1

Remove the last item from a list.

>>> print(fruits)
['bannanas', 'melons', 'coconuts', 'pineapple']
>>> fruits.pop()
'pineapple'
>>> print(fruits)
['bannanas', 'melons', 'coconuts']

Sort a list alphabetically.
Print the current order of the list.

>>> print(fruits)
['bannanas', 'melons', 'coconuts']

Order after running the sort method.

>>> fruits.sort()
>>> print(fruits)
['bannanas', 'coconuts', 'melons']

Let's remove coconuts from the list.

>>> fruits.remove("coconuts")
>>> print(fruits)
['bannanas', 'melons']
