Question

1. Modify the draw() function in the Creature class so that instead of being displayed as a square, the creature is displayed as a triangle.

## A creature draws itself using the colour specified as part of its dna
## the size of the grid squares, and the position of the top-left pixel are provided as input
def draw(self, grid_size, top_left_x, top_left_y):

## Compute the position of the top left hand corner of the cell this creature is in
x = top_left_x + (self.col-1)*grid_size
y = top_left_y - (self.row-1)*grid_size
turtle.color(self.dna[0].split(":")[1])

## Draw the creature
turtle.goto(x, y)
turtle.pendown()
turtle.begin_fill()
turtle.goto(x + grid_size, y)
turtle.goto(x + grid_size, y - grid_size)
turtle.goto(x, y - grid_size)
turtle.goto(x, y)
turtle.end_fill()
turtle.penup()
turtle.color("black")
