Code a Grade Calculator with Functions in Python

Level: Beginner

Your task for today is to build a Grade Calculator that processes a list of scores using functions. This project will help you practice defining and calling functions, handling input validation, and formatting results in a clear way.

📝 Project Task

The program should:

• Define a function that takes a list of scores and returns:

  • The average score (rounded to 2 decimals).

  • The letter grade (A, B, C, D, F).

  • Whether the student passed or failed (e.g., pass if ≥ 60).

• Prompt the user to enter multiple scores separated by commas.

• Validate input (only allow numeric values between 0 and 100).

• Print results in a formatted style.

Bonus (optional):

• Support multiple students by repeating the input prompt in a loop.

• Save results to a text or CSV file.

This project strengthens your skills with functions, conditional logic, and user input validation.

📌 Expected Output

When run, the program should behave like this:

If the input is invalid:
