[开发工具]python画美国队长盾牌——turtle库

?盾牌用turtle库里的circle（），十分逼真！

代码如下：

import turtle as t


def setpen(x, y):

    t.penup()
    t.goto(x, y)
    t.pendown()
    t.setheading(0)

def circle(x, y, r, color):

    n = 36
    angle = (360 / n)
    pi = 3
    c = ((2 * pi) * r)
    l = (c / n)
    start_x = (x - l / 2)
    start_y = (y + r)
    setpen(start_x, start_y)
    t.pencolor(color)
    t.fillcolor(color)
    t.begin_fill()
    for i in range(n):
        t.forward(l)
        t.right(angle)
    t.end_fill()

def five_star(l):

    setpen(0, 0)
    t.setheading(162)
    t.forward(150)
    t.setheading(0)
    t.fillcolor('WhiteSmoke')
    t.begin_fill()
    t.hideturtle()
    t.penup()
    for i in range(5):
        t.forward(l)
        t.right(144)
    t.end_fill()

def sheild():

    circle(0, 0, 300, 'red')
    circle(0, 0, 250, 'white')
    circle(0, 0, 200, 'red')
    circle(0, 0, 150, 'blue')
    five_star(284)

if (__name__ == '__main__'):
    sheild()
