Stepping and Negative
Lesson 14 of 19 in Coddy's Into the Past || Complete Beginner for Python Strings course.
Below you can also see a set of negative number below the positive ones. Python is also capable of negative indexing. What that means is you can index in reverse. More specifically the letter e has an index of 4 and -2. Along with negative indexing, you can use the step argument to step through a string in reverse

letters = "abcdef"
letters[5:2:-1] --> "fed"
letters[-1:-4:-1] --> "fed"
As you can see there is more than one way to slice a string
