Make Turtle Art! 🎨🐢

Today we become real artists! 🖼️ We'll combine colors, shapes, and loops to make a beautiful PATTERN.

A pattern is something that repeats in a cool way. Let's create masterpieces! 🤩

import turtle

t = turtle.Turtle()
t.speed(0)
t.circle(50)

Spinning Squares 🟦🌀

Let's draw a square, turn a little, and repeat! The squares spin into a flower pattern. 💠

We draw a square (4 sides) inside a loop that turns each time.

import turtle

t = turtle.Turtle()
t.speed(0)
for i in range(12):
    for s in range(4):
        t.forward(80)
        t.right(90)
    t.right(30)

A Loop Inside a Loop! 🔁🔁

Whoa, did you see TWO loops? 😮 The inside loop draws one square. The outside loop spins it around!

This is called a loop inside a loop. Super powerful for patterns! 💪

import turtle

t = turtle.Turtle()
t.speed(0)
for i in range(6):
    for s in range(3):
        t.forward(90)
        t.right(120)
    t.right(60)

Add Rainbow Colors! 🌈

Let's pick a new color each time the pattern spins. 🎨

We make a list of colors and use colors[i] to pick one each loop.

import turtle

t = turtle.Turtle()
t.speed(0)
colors = ['red', 'orange', 'yellow', 'green', 'blue', 'purple']
for i in range(6):
    t.pencolor(colors[i])
    t.circle(70)
    t.right(60)

A Rainbow Spiral 🌀🌈

Spirals are magic! We go forward a little MORE each time and turn. 🌪️

Watch it grow bigger and bigger in rainbow colors!

import turtle

t = turtle.Turtle()
t.speed(0)
colors = ['red', 'orange', 'yellow', 'green', 'blue', 'purple']
for i in range(60):
    t.pencolor(colors[i % 6])
    t.forward(i * 2)
    t.right(59)

What Is i % 6?

That funny i % 6 gives the remainder when dividing by 6. It goes 0,1,2,3,4,5,0,1,2... 🔄

This lets us cycle through our 6 colors forever! The rainbow never runs out! 🌈

for i in range(8):
    print(i % 3)

A Field of Stars ⭐⭐⭐

Let's spin a star around! A star turns 144 degrees at each point.

Draw a star, turn a bit, repeat. A galaxy of stars! 🌌

import turtle

t = turtle.Turtle()
t.speed(0)
t.pencolor('gold')
for i in range(10):
    for p in range(5):
        t.forward(60)
        t.right(144)
    t.right(36)

Fill the Pattern With Color 🪣

Remember begin_fill and end_fill? Let's fill our spinning triangles! 🔺

Each triangle gets poured full of color as it spins. Gorgeous! 💜

import turtle

t = turtle.Turtle()
t.speed(0)
t.fillcolor('violet')
for i in range(8):
    t.begin_fill()
    for s in range(3):
        t.forward(70)
        t.right(120)
    t.end_fill()
    t.right(45)

Add a Background 🖼️

A dark background makes bright colors POP! ✨

Use turtle.bgcolor('black') and watch your neon pattern glow! 🌟

import turtle

turtle.bgcolor('black')
t = turtle.Turtle()
t.speed(0)
colors = ['cyan', 'magenta', 'yellow', 'lime']
for i in range(40):
    t.pencolor(colors[i % 4])
    t.forward(i * 3)
    t.right(91)

Tip: Speed 0 Is Fastest 🏎️

Patterns have LOTS of lines. To see them quickly, always use t.speed(0)! 💨

That's the fastest setting. Your art appears in a flash! ⚡

import turtle

t = turtle.Turtle()
t.speed(0)
for i in range(36):
    t.forward(100)
    t.right(170)

Create Your Masterpiece! 🎨🌟

Now make YOUR pattern! Change the colors, the number of repeats, and the turn angle. 🤩

Try different numbers in right(...) and range(...). Every change makes new art! 🖼️

import turtle

turtle.bgcolor('navy')
t = turtle.Turtle()
t.speed(0)
colors = ['white', 'pink', 'cyan']
for i in range(50):
    t.pencolor(colors[i % 3])
    t.forward(i * 2)
    t.right(89)
