🎨 Lesson 5: Drawing with Turtle

📘 What is Turtle?

turtle is a built-in Python library that provides a way to draw using code. It opens a window and shows a turtle icon that you can control to draw shapes and patterns.

It’s especially useful for beginners to understand loops, movement, and even angles while creating visual feedback instantly.

🔧 Setting Up Turtle

To use turtle, you don't need to install anything if you're using standard Python. Just use import turtle in your code. Make sure you're running your script in a Python environment that supports graphical output (like a local IDE, not most online editors).

💻 Basic Example

import turtle

# Create screen and turtle object
window = turtle.Screen()
my_turtle = turtle.Turtle()

# Draw an L-shape
my_turtle.forward(100)
my_turtle.left(90)
my_turtle.forward(100)

# Keep the window open
window.mainloop()

This code opens a window and makes the turtle draw an L-shape.

🧠 Try It Yourself

• Draw a square using a for loop.
• Change the turtle's color using my_turtle.pencolor("blue").
• Make the turtle draw a triangle or star.

📘 Tips & Tricks

• my_turtle.speed(1) sets how fast the turtle moves.
• my_turtle.penup() and pendown() allow you to move the turtle without drawing.
• window.bgcolor("lightblue") changes the background color.

📝 Assignment

Write a Python program that uses the turtle module to draw a simple house:

• Draw a square as the base of the house.
• Draw a triangle roof on top.
• Use different colors for the house and the roof.
