Python实现七彩蟒蛇绘制实例代码

#蟒蛇绘制
import turtle

def drawSnake(rad,angle,len,neckrad):
  for i in range(len):
    turtle.circle(rad,angle) #画圆 rad：圆半径 angle：圆弧度
    turtle.circle(-rad,angle) #运行轨迹右侧rad远的地方绘制圆
  turtle.circle(rad,angle/2)
  turtle.fd(rad) #表示直线爬行，forward，参数表示爬行的距离
  turtle.circle(neckrad+1,180)
  turtle.fd(rad*2/3)

def main():
  turtle.setup(1300,800,0,0) #设置窗口宽+高+起始位置
  pythonsize = 30
  turtle.pensize(pythonsize) #设置笔的宽度
  turtle.pencolor("blue") #设置笔的颜色
  turtle.seth(-40) #设置笔的起始角度
  drawSnake(40,80,5,pythonsize/2)

#蟒蛇绘制
import turtle

def drawSnake(rad,angle,len,neckrad):

  colors = ["red","orange","yellow","green","cyan","blue"]
  for i in range(len):
    turtle.color(colors[i])
    turtle.circle(rad,angle)
    turtle.circle(-rad,angle)

  turtle.color("purple")
  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)
  turtle.penup()
  turtle.goto(-350,0)
  turtle.pendown()
  pythonsize = 30
  turtle.pensize(pythonsize)
  turtle.seth(-40)
  drawSnake(40,80,6,pythonsize/2)
