The error message is telling you that there is no such element in the array you are assigning to:
hours_worked[emp_count] = int(input('Hours >'))
And that is because the array has no elements when you start:
hours_worked = 
Instead of assuming an element exists when you try to add a new employee (which is won't as you are trying to create it!) append the new employee data to the array:
Quote:Hi, and thank you so much for helping!
However, as I tried this solution, another error popped up: TypeError: show_employees() missing 1 required positional argument: 'employee_id'. I have updated the code in the question, and the problem seems to be coming from line 58.
You should expect to get syntax errors every day, probably many times a day while you are coding - we all do regardless of how much experience we have! Sometimes, we misspell a variable, or a keyword; sometimes we forget to close a string or a code block. Sometimes the cat walks over your keyboard and types something really weird. Sometimes we just forget how many parameters a method call needs.
We all make mistakes.
And because we all do it, we all have to fix syntax errors - and it's a lot quicker to learn how and fix them yourself than to wait for someone else to fix them for you! So invest a little time in learning how to read error messages, and how to interpret your code as written in the light of what the compiler is telling you is wrong - it really is trying to be helpful!
So read this: How to Write Code to Solve a Problem, A Beginner's Guide Part 2: Syntax Errors
] - it should help you next time you get a compilation error!
And spending a little time learning to understand syntax error messages will save you a huge amount of time in future: you waited at least 25 minutes for me to reply, then your email system probably added another 10 minutes or so, plus the time it took you to type up the question. Chances are that you could have saved a significant chunk of that time if you knew how to read them!
I'm not saying we don't want to help you fix them - sometimes I can't see my own errors because I read what I meant to write - but fixing syntax errors is part of the job, and if you can't do it for yourself people are going to look at you as a bit weird should you get a job in the industry!
In this case look at where you define the function and where you use it, and combine that with the error message and it should be pretty obvious what you forgot!
