Let's Build a House! 🏠🐢

Today we start building a house with our turtle! 🏗️ First we need WALLS.

A house wall is just a big square. Let's draw one step by step! 🟦

import turtle

t = turtle.Turtle()
t.forward(100)

One Wall at a Time

The turtle starts by drawing the bottom of the house. It goes forward(100). ➡️

That's the floor of our house! 🏠

import turtle

t = turtle.Turtle()
t.forward(120)

Turn to Go Up ⬆️

After the bottom, we turn LEFT to go up the wall.

t.left(90) turns a quarter circle, so now the turtle points up! Then it goes forward again.

import turtle

t = turtle.Turtle()
t.forward(120)
t.left(90)
t.forward(120)

Across the Top

Now turn left again and draw the top of the house. 🏠

Each corner is a left(90) turn. We're going around the square!

import turtle

t = turtle.Turtle()
t.forward(120)
t.left(90)
t.forward(120)
t.left(90)
t.forward(120)

Close the Square ⬜

One more turn and one more wall, and the square is closed! 🎉

Four sides, four turns. That's our house frame!

import turtle

t = turtle.Turtle()
t.forward(120)
t.left(90)
t.forward(120)
t.left(90)
t.forward(120)
t.left(90)
t.forward(120)

The Easier Way: A Loop! 🔁

Writing forward and left 4 times is a lot! 😮‍💨 Let's use a loop instead.

for i in range(4): repeats the wall and turn 4 times. Same square, less typing! 🙌

import turtle

t = turtle.Turtle()
for i in range(4):
    t.forward(120)
    t.left(90)

Color the Walls 🎨

A house needs color! Let's make the walls brown like wood. 🟤

Use t.pencolor('brown') before we draw.

import turtle

t = turtle.Turtle()
t.pencolor('brown')
for i in range(4):
    t.forward(120)
    t.left(90)

Fill the House With Color 🪣

Let's paint the house yellow inside! 💛

Use begin_fill() before the loop and end_fill() after. The whole square fills in!

import turtle

t = turtle.Turtle()
t.fillcolor('yellow')
t.begin_fill()
for i in range(4):
    t.forward(120)
    t.left(90)
t.end_fill()

Make the Lines Thicker ✒️

Strong houses need strong walls! Use t.pensize(4) to make thick lines. 💪

Bigger number = thicker wall.

import turtle

t = turtle.Turtle()
t.pensize(4)
t.fillcolor('lightyellow')
t.begin_fill()
for i in range(4):
    t.forward(120)
    t.left(90)
t.end_fill()

A Bigger House 🏰

Want a bigger house? Just make the number in forward bigger! 📏

Try forward(150) for a mansion! 🏰

import turtle

t = turtle.Turtle()
t.fillcolor('orange')
t.begin_fill()
for i in range(4):
    t.forward(150)
    t.left(90)
t.end_fill()

Build Your Own Walls! 🏠

Your turn! Pick a fill color and a size for YOUR house. 🎨

Change 'pink' and the number in forward to whatever you like! 🩷

import turtle

t = turtle.Turtle()
t.fillcolor('pink')
t.begin_fill()
for i in range(4):
    t.forward(130)
    t.left(90)
t.end_fill()
