6.2 List Indexing

List Indexing

Each element is stored at a certain index, or position, in the list.
Using my_list, this is what the indexes to elements would look like.
index
  • 0
  • 1
  • 2
  • 3
  • 4
element
  • 1
  • 2
  • "oh no"
  • 4
  • 5.62
You can also get certain elements from a list by indexing it:
my_list = [1, 2, "oh no", 4, 5.62] print(my_list[1]) # prints 2 print(my_list[3]) # prints 4 # you could also print my_list, which would print all the elements
You can also use a negative index. This retrieves elements, starting the count from the back of the list
my_list = [1, 2, "oh no", 4, 5.62] print(my_list[-1]) # pints 5.62 print(my_list[-4]) # prints 2

An alternative for negative indexes is the following: my_list[len(my_list)-1]. This example would get the last item. However, it is much more elegant to use negative indexes.
