How to draw a polygon given a number of points with Turtle()?

August 20, 2022

I have a list of points given by (x, y) coordinates, and I want to connect them in a polygon shape. For example:

import turtle
    
tina = turtle.Turtle()
tina.shape('turtle')
    
points = [
    (40, -80),
    (30, -80),
    (30, -70),
    (40, -70)
]

Is there a function for drawing polygons like turtle.circle()?

>Solution :

Try the following:

import turtle

tina=turtle.Turtle()
tina.shape("turtle")

points=[[10,-80],[200,-80], [100, 100]]

# Draw a polygon based on the points list in points and #show the result
def draw_polygon(points):
    tina.penup()
    tina.goto(points[0])
    tina.pendown()
    for point in points:
        tina.goto(point)

    tina.goto(points[0])  # Go back to the origin to close the polygon shape


draw_polygon(points)

turtle.done()

However, it draws only in the order the points are given – so that order needs to be correctly specified in order to get a polygon.
