Coding — Debugging — Part 10 Learn the concept, study the code, then try the challenge! 💻 Debugging Every programmer finds bugs. The key is a systematic approach to fixing them. Code Example: # Can you spot the bug? total = 0 for i in range(1, 5): total = total + 1 # Should add i print('Sum:', total) Steps: 1. Read the error message (if any) 2. Check spelling and capitalization 3. Look at indentation and colons 4. Print values to see what's happening 5. Fix one thing, then test again 🚀 Try It! The code should print the sum 1+2+3+4=10 but prints 4. Fix the bug. 🐛 Debug Challenge: for i in range(10): print(i) — prints 0–9 instead of 1–10. Fix it!
