import turtle

def drawSnake(rad, angle, len, neckrad):
for i in range(len):
turtle.circle(rad,angle)
turtle.circle(-rad,angle)
turtle.circle(rad, angle/2)
turtle.fd(rad)
turtle.circle(neckrad+1, 180)
turtle.fd(rad*2/3)

def main():
turtle.setup(1300,800, 0, 0)
pythonsize = 30
turtle.pensize(pythonsize)
turtle.pencolor("blue")
turtle.seth(-40)
drawSnake(40,80,5,pythonsize/2)

main()
