Tips

• Each exercise file has questions as comments — write your answer directly below.
• Run your file often: python exercises/grade-1/grade_1.py
• If something goes wrong, read the traceback bottom to top — the last line tells you the error.
• Commit your work as you go. Your fork becomes a portfolio of your progress.
