I wrote the move function of this phython code: but it is not working here correctly, Karel is only moving one space.
Here are the directions:
YOUR JOB
Karel doesn’t know how to move! Since we aren’t using the built in Karel commands, we’ll have to make the image of Karel move using Python!

Your job is to implement the move() function.

You do not need to worry about running into walls.

You do not need to modify any of the other code function. The final result should have Karel move forward (east) twice, then move in a square. Karel should end on the first street, fourth avenue, facing south.

HINTS
Your move function should change the X_POS and Y_POS variable based on the direction that Karel is facing. For example, if direction is NORTH, then Karel should move in the negative y direction. If direction is SOUTH, then Karel should move in the positive y direction, etc.

Once you update the X_POS or Y_POS, you can then set a new position by calling the .set_position method.

Karel should move a distance of KAREL_SIZE.
