# 11.38 (Turtle: draw a polygon/polyline) Write the following functions that draw a
# polygon/polyline to connect all points in the list. Each element in the list is a list of
# two coordinates.
# # Draw a polyline to connect all the points in the list
# def drawPolyline(points):
# # Draw a polygon to connect all the points in the list and
# # close the polygon by connecting the first point with the last point
# def drawPolygon(points):
# # Fill a polygon by connecting all the points in the list
# def fillPolygon(points):
import turtle
# Draw a polyline to connect all the points in the list
def drawPolyline(points):
for i in range(len(points) - 1):
drawLine(points[i], points[i + 1])
# Draw a polygon to connect all the points in the list and
# close the polygon by connecting the first point with the last point
def drawPolygon(points):
drawPolyline(points)

# Fill a polygon by connecting all the points in the list
