notation

[MCL169]

If split creates a lists of strings is [0] the first line in the file or the first item in a list?

What is lines in the first place?
Anyway, in case like you can simply add some print calls to see for yourself. And actually the comments suggest you already did that, so your question (or confusion) is unclear.

Yeah I'm sorry it might seem like I'm just going through the motions but what it is my professor is very anal about stuff like that and I just was not sure how to notate that particular line of code but it is running correctly.
