""" There should be a description of why this reverses the list

In python, you can specify steps by using a third index. If you don't specify the first or second index and the third one is negative, it will return the characters jumping and backwards. 
Reversing a string as a result of omiting the first and second indices and designate a minus one step is a very common strategy.
Styntax: [start, stop, step]
