Your First Challenge

Let's walk through what to expect in your first CodeGuessr challenge.

Example Challenge

# Python
numbers = [1, 2, 3, 4, 5]
result = sum(numbers) / len(numbers)
print(f"Average: {result:.1f}")

Question: What will this code output when run?

How to Approach It

  1. Read the code line by line:
    • numbers = [1, 2, 3, 4, 5] creates a list
    • sum(numbers) adds all numbers: 1+2+3+4+5 = 15
    • len(numbers) counts items: 5
    • result = 15 / 5 = 3.0
  2. Understand the output format:
    • f"Average: {result:.1f}" formats the number to 1 decimal place
    • So 3.0 becomes "Average: 3.0"
  3. Submit your answer: Type "Average: 3.0" and click submit

Understanding Feedback

CodeGuessr uses Wordle-style color feedback to help you learn from each guess.

Blue - Correct: This character is correct and in the right position.

Purple - Wrong Position: This character exists in the answer but in a different position.

Red - Not Present: This character is not in the correct answer at all.

Pro Tips

  • Pay attention to spaces, punctuation, and capitalization
  • Use each guess to eliminate possibilities
  • Blue feedback is your friend - keep those characters!
  • Purple feedback means you're close - try different positions
