Originally, the turtle was a robot
It moved around the floor when the user typed commands into a computer.
Today, it is a picture on the canvas drawing area in Python
The default turtle is drawn as a triangle but this can be changed in the code
The Screen() function creates a graphics window.
The graphics window contains a canvas, this is the area inside the window which the turtle draws the lines and shapes on.
The turtle is moved using a combination of X and Y co‐ordinates and left or right turns.
the graphic below illustrates the principle.
