Help! How do you do this?

I just answered on your question a while back. Perhaps I wasn't clear enough, but let me start from beginning.

Lets understand something called Arrays.

Arrays are nothing but a continuos collection of similar type of values.

Example:

variable1= ['A', 'B', 'C', 'd', 'e']

Variable1 is collection of letters, and how do you use this Array and why would you use it.

Well, to answer that question, i'll tell you to think of a situation where you have to store a collection of similar value but use them independently as well, storing in many different variable doesn't make sense. Now, for how to use it... simply variable1[0] will give you 'A'.(indexing starts from zero.) similarly variable1[1]='B'... and so on.

Now there could be a collection of any type of value, string, integer, float, arrays or arraysOfArrays... you name it.

In python everything is an Object.

Lists are nothing but arrays in Python. A string can also be treated like a list in python.

But what is different in Python is its Reverse-Index or Backward Index. The front index starts from 0(zero) as seen in above example, but if you need to access the last value???

Simple start indexing from -1, so...

#variable1[-1] is nothing but  'e'
#Similarly, variable1[-2] is 'd'
# and so on...

Hope this helps. If you find it helpful, upvote it for others and if not then please do comment you doubts below.

Have fun coding.
