Abstract

turtle is located at position 0,0. (this position is the center of the screen and is called home() ). If we want to draw a circle with a radius of 100 pixels centered at 0,0 we would have to move the turtle to an outside edge and since we don’t want to show a line we would have to pick up the pen; then turn the turtle to the left 90 degrees; put the pen back down and draw the circle.<div id="f2aa"><pre>import turtle as T T.penup () T.forward (100) T.left (90) T.pendown() T.circle (100)</pre></div>Now, let’s use the circle command to create the Olympic rings.<div id="c66b"><pre>import turtle as T T.width (10)</pre></div><div id="98b1"><pre>T.circle (100) # A black circle set above center.</pre></div><div id="4621"><pre>T.penup() T.goto (-215,0) # we factor in the thickness of line and space T.pendown() between circles.

Drawing The Olympic Rings With Python Turtle

Continuing lesson on the circle command.

In a previous lesson, we introduced the circle command in Python Turtle now we are going to explore a bit further.

The circle command goes from the current position of the turtle and draws a circle with a given radius moving counterclockwise. if the radius is entered as a negative number it goes clockwise.

Here’s a drawing of a pair of semicircles to illustrate.

import turtle as T
T.width (10)
T.color ("blue")
T. circle (50,180)
T.color ("red")
T. circle (-50,180)

When drawing a circle we frequently want to draw the circle from the center.

Here is one way to accomplish this. We will look at another way in another lesson.

The turtle is located at position 0,0. (this position is the center of the screen and is called home() ). If we want to draw a circle with a radius of 100 pixels centered at 0,0 we would have to move the turtle to an outside edge and since we don’t want to show a line we would have to pick up the pen; then turn the turtle to the left 90 degrees; put the pen back down and draw the circle.

import turtle as T
T.penup ()
T.forward (100)
T.left (90)
T.pendown()
T.circle (100)

Now, let’s use the circle command to create the Olympic rings.

import turtle as T
T.width (10)

T.circle (100) # A black circle set above center.

T.penup()
T.goto (-215,0) # we factor in the thickness of line and space
T.pendown()      between circles.
T.color ("blue")
T.circle (100)

T.penup()
T.goto (215,0)
T.pendown()
T.color ("red")
T.circle (100)

T.penup()
T.goto (-115,-100)
T.pendown()
T.color ("yellow")
T.circle (100)

T.penup()
T.goto (115,-100)
T.pendown()
T.color ("green")
T.circle (100)
