Shapes and Fills

Drawing and Filling Shapes

Now that we've learned how to move the turtle around the screen we can move onto drawing and filling shapes.

To draw a circle we can use:

• .circle(radius)

To fill shapes we must play a .begin_fill() where would like to start filling and a .end_fill() where we would like to stop.

import turtle

tim = turtle.Turtle()
tim.color("red", "blue")  # Blue is the fill color

tim.width(5)

tim.begin_fill()
tim.circle(50)
tim.end_fill()  

This results in the following image.

In the last tutorial I showed you how to draw a square using a series of turtle commands. An easier way uses a for loop and can be seen below.

import turtle

tim = turtle.Turtle()
tim.color("red", "blue")  # Blue is the fill color

tim.width(5)

tim.begin_fill()
for x in range(4):  # This will draw a square filled in
    tim.forward(100)
    tim.right(90)

tim.end_fill()

A new command that we can use to set the absolute position of the turtle object is .setpos(x, y).

tim.setpos(100, -50)

Example

The following program will randomly draw shapes on the screen.

import turtle
import random

colors = ["red", "blue","green", "purple", "yellow", "orange", "black"]

tim = turtle.Turtle()
tim.color("red", "blue")

for x in range(5):
    randColor = random.randrange(0, len(colors))
    rand1 = random.randrange(-300,300)
    rand2 = random.randrange(-300,300)
   
    tim.color(colors[randColor], colors[random.randrange(0, len(colors))])

    tim.penup()
    tim.setpos((rand1, rand2))
    tim.pendown()
    
    tim.begin_fill()
    tim.circle(random.randrange(0,80))
    tim.end_fill()
    ```
