Tutorial 3: Smart Bearcu

Learning Goal: Conditionals (If/Else)

Sometimes you need to make decisions in your code. Should Bearcu move forward or turn? It depends on whether there's a wall!

The if statement lets you run code only when a condition is true. The else statement runs when the condition is false.

if bearcu.can_move():
    bearcu.move_forward()  # Only if path is clear
else:
    bearcu.turn_right()     # If there's a wall

You can also use not to check the opposite:

if not bearcu.can_move():
    bearcu.say("Wall ahead!")  # If there IS a wall

Tutorial 3: Smart Bearcu

Bearcu encounters a wall blocking the direct path to the star! You need to check if Bearcu can move before moving. If there's a wall, you'll need to go around it. Use bearcu.can_move() to check if the path ahead is clear, and bearcu.turn_right() or bearcu.turn_left() to change direction.

What You Learned

  • Use if to run code conditionally
  • Use else to handle the alternative case
  • bearcu.can_move() returns True or False
  • not reverses a boolean value
  • Combine conditionals with loops for smart behavior
