1.3 UNDERSTANDING SCREEN AND TURTLE(PEN)
Gowri: In the file that we just opened to draw a shape using Turtle, we need to write a few
commands to prepare our canvas and pen for drawing.

The CODING AREA is the place where we write the instructions for drawing shapes.
The SCREEN AREA is the place where we actually see the shape (output) that we draw using
instructions.
The Turtle ➤ that we see in the middle of screen area (canvas) is actually the PEN. By moving this
pen in different directions, we can draw rectangles, triangles, squares, circles, stars, and more.

Aryan: It seems very interesting. Please show me how to draw these using this pen shaped
turtle.. now I am also loving this idea of yours. It is really SUPER COOL!

Gowri: To begin this, you need to write the following lines:

import turtle → to start the working of turtle
scr=turtle.Screen() → to prepare the screen or canvas for drawing

pen=turtle.Turtle() → to get the pen ready for drawing

1.4 INTRODUCTION TO PROGRAMMING WITH TURTLE

Gowri: If I ask you to draw a line in your notebook, what would you do?

Aryan: Hey ..It is not funny I know..I will take a blank sheet of paper
and a pen, then make a line in any direction- it's as simple as that.
Gowri: Exactly! It's just as simple with Turtle. Look, I will show you;
Think of the CANVAS/SCREEN as your paper, and the turtle pen as
your on-screen pen. The commands you give will make the line appear on
the screen.
