Working with Lists in Python
Selecting List Elements II
What if we want to select the last element of a list?
We can use the index -1 to select the last item of a list, even when we don’t know how many elements are in a list.
Consider the following list with 5 elements:
list1 = ['a', 'b', 'c', 'd', 'e']If we select the -1 element, we get the final element, 'e':
>>> print(list1[-1])
'e'This is the same as selecting the element with index 4:
>>> print(list1[4])
'e'Instructions
1.
Use print and len to display the length of shopping_list.
2.
Get the last element of shopping_list using the -1 index. Save this element to the variable last_element.
3.
Now select the element with index 5 and save it to the variable element5.
4.
Use print to display both element5 and last_element.
