Hello! What I am trying to do, is the following:
This program opens a file, where it is supposed to read lines of data (Which right now it does fine, in correct order), and validate the name, to ensure that line where the name would be is not empty. However, when I try to validate it, it essentially ignores my validation and proceeds like it's not even there. How can I get it to work?
Thanks in advance!

On line 23 where you check if there name == ''. Try putting a space in between the quotes

Thanks for your response.
I just tried that, but it still does the same thing. Here's how it is displayed.

Welcome to Academic Helper 2,0.
This program determines the grade you would get or the number of hours you need to study

Sry for late response but I noticed somethign in optionA - it says while name != '' and then inside the name verification it says while name == ''

---

I'm testing it right now.

Could you tell me what is in the text document

I got it working.
I needed to strip \n, and now it works perfectly.

I attached code for the reference.
Thanks for trying!
