Reversing a List
We have seen that a positive stride progresses through the list from left to right.
A negative stride progresses through the list from right to left.
letters = ['A', 'B', 'C', 'D', 'E'] print letters[::-1]
In the example above, we print out ['E', 'D', 'C', 'B', 'A']
.
Instructions
1.
Create a variable called backwards
and set it equal to the reversed version of my_list
.
Make sure to reverse the list in the editor by passing your list slice a negative stride, like in the example above.
