Meet the Color Turtle! 🐢🎨

Get ready to paint with a turtle! 🐢 In Python we have a tool called turtle that lets us draw on the screen.

The turtle holds a magic pen. When it walks, it leaves a colorful line behind it! ✏️🌈

import turtle

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

A Pen That Changes Color

Right now the turtle draws in black. Boring! 😴

We can change the pen color with t.pencolor('red'). Now everything it draws is RED! ❤️

import turtle

t = turtle.Turtle()
t.pencolor('red')
t.forward(100)

So Many Colors! 🌈

You can pick lots of colors by name:

'red' ❤️
'blue' 💙
'green' 💚
'purple' 💜
'orange' 🧡

Just put the color name inside the quotes!

import turtle

t = turtle.Turtle()
t.pencolor('blue')
t.forward(120)

Change Color Anytime

You can change colors as many times as you want while drawing! 🎨

Draw a bit in one color, switch, then draw more in another color. Watch the rainbow appear!

import turtle

t = turtle.Turtle()
t.pencolor('red')
t.forward(60)
t.pencolor('green')
t.forward(60)

Make the Pen Thicker ✒️

A thin line is hard to see. Let's make a fat pen!

Use t.pensize(5). The bigger the number, the thicker the line! Try 10 for super chunky lines. 💪

import turtle

t = turtle.Turtle()
t.pensize(8)
t.pencolor('purple')
t.forward(100)

Turn and Color a Corner

Let's draw a colorful corner! 📐

Move forward, turn with t.right(90) (a quarter turn), then move again in a new color.

import turtle

t = turtle.Turtle()
t.pencolor('orange')
t.forward(80)
t.right(90)
t.pencolor('blue')
t.forward(80)

A Colorful Triangle 🔺

Three sides, three colors! Let's draw a triangle where each side is a different color.

We turn 120 degrees at each corner to make a triangle.

import turtle

t = turtle.Turtle()
t.pencolor('red')
t.forward(100)
t.left(120)
t.pencolor('green')
t.forward(100)
t.left(120)
t.pencolor('blue')
t.forward(100)

Change the Background 🖼️

You can even color the WHOLE screen behind your turtle!

Use turtle.bgcolor('lightblue'). Now your drawing has a sky behind it! ☁️

import turtle

turtle.bgcolor('lightblue')
t = turtle.Turtle()
t.pencolor('yellow')
t.forward(100)

Speed It Up! 🏎️

Want your turtle to draw FAST? Use t.speed(0) for super speed! 💨

Or t.speed(1) to watch it go slow and see every step.

import turtle

t = turtle.Turtle()
t.speed(0)
t.pencolor('magenta')
t.forward(150)

Color Names Are Just Words

Remember: the color goes inside quotes like 'pink'. 🩷

If you spell it wrong (like 'redd'), the turtle gets confused! Spelling matters. ✅

import turtle

t = turtle.Turtle()
t.pencolor('pink')
t.pensize(6)
t.forward(100)

Make Your Own Color Line!

Now YOU choose! Pick your favorite color and a pen size. 🌟

Change 'green' to any color you like and change the number in pensize. Have fun! 🎉

import turtle

t = turtle.Turtle()
t.pensize(10)
t.pencolor('green')
t.forward(140)
