Python code for olympic rings :
import turtle
class MyTurtleOly(turtle.Turtle):
""""""
def __init__(self):
""" Constructor"""
turtle.Turtle.__init__(self, shape="turtle")
def drawCircle(self, x, y, radius=50):
"""
Moves the turtle to draw a circle
"""
self.penup()
self.setposition(x, y)
self.pendown()
self.circle(radius)
def drawOlympicSymbol(self):
"""
Iterates to draw the Olympics logo
"""
positions = [(0, 0), (-120, 0), (60,60),
(-60, 60), (-180, 60)]
for position in positions:
self.drawCircle(position[0], position[1])
if __name__ == "__main__":
t = MyTurtleOly()
t.drawOlympicSymbol()
turtle.getscreen()._root.mainloop()
Python code for star :
import turtle
def drawStar(size, color):
angle = 120
turtle.fillcolor(color)
turtle.begin_fill()
for side in range(5):
turtle.forward(size)
turtle.right(angle)
turtle.forward(size)
turtle.right(72 - angle)
turtle.end_fill()
return
drawStar(100, "purple")
