function help (totaly beginner)

[thanikos]

So you take a letter of the word and you get the index of that letter in the list and move it to the right - add 1 to the index. Check if the letter is the last one and take the first one if that is the case. Otherwise, you get an error: List index out of range.

Thank you wavic.
I am on an online course that i have regret. The help i gett is almost zero and the book i got is not completely accurate to the assigments.
I feel that if i see this assigment solved i will get unstuck. I will try to continue the course in the classroom next year.
I hope that you can help me a little bit more but i understand if you wont.
cheers!
