Question

2.12.6: Right vs. Left Square

Write a program that has Karel place balls in a square formation.

If Karel is facing North to start, balls should be placed in a square using right turns only [(put ball, move, turn right) x4]. You should write a function called makeRightSquare to accomplish this.
If Karel is facing East to start, balls should be placed in a square using left turns only [(put ball, move, turn left) x4]. You should write a function called makeLeftSquare to accomplish this.
In both scenarios, Karel should end facing the starting direction.

Practice using an if/else statement in your code. You should also use a for loop in your solution!

hope that helps.!

Explanation: ``python def makeRightSquare(): for i in range(4): put_ball() move() turn_right() turn_right() def makeLeftSquare(): for i in range(4): put_ball() move() turn_left() turn_left() # Check Karel's starting direction if facing_north(): makeRightSquare() elif facing_east(): makeLeftSquare() ``` In this program, we have two functions: `makeRightSquare()` and `makeLeftSquare()`. These functions use a for loop to repeat the actions of putting a ball, moving forward, and turning either right or left depending on the starting direction of Karel. Based on Karel's starting direction, we use an if/else statement to call the appropriate function (`makeRightSquare()` or `makeLeftSquare()`). If Karel is facing north, `makeRightSquare()` is called, which uses right turns to create the square formation. If Karel is facing east, `makeLeftSquare()` is called, which uses left turns. At the end of each function, Karel turns back to the starting direction so that the final position matches the initial direction. Remember to replace the `put_ball()`, `move()`, `turn_right()`, `turn_left()`, `facing_north()`, and `facing_east()` with the actual functions and conditions specific to the programming environment or language you are using.What would you like to do next?
