When things go wrong, Python tries to be helpful by providing a 
"traceback". Please copy-paste the entire traceback, to help us help you.

The error-message says that (somewhere) a list is being used *but* the 
index is pointing to an element that does not exist, eg the fifth 
element of a list that contains only three members.

Short answer: What you could do, is add a temporary print() to show you 
the exact value of the list index. Thus, giving you a pointer/where to 
back-track, to find the source of the problem...

The longer answer: learning to use a debugger or a 'visual' IDE/web-tool.
