本文主要向大家介绍了用Python语言的turtle模块画国旗，通过具体的内容向大家展示，希望对大家学习Python语言有所帮助。

最近在学Python，发现Python的海龟绘图非常有趣，就分享一下！话不多说，先来Python turtle的官方文档链接： Python turtle。这里面有turtle的各类指令。turtle画国旗主要用到两个函数：draw_rentangle和draw_star。import time
import turtle
import os
def draw_rectangle(start_x,start_y,rec_x,rec_y):
    turtle.goto(start_x,start_y)
    turtle.color('red')
    turtle.fillcolor('red')
    turtle.begin_fill()
    for i in range(2):
        turtle.forward(rec_x)
        turtle.left(90)
        turtle.forward(rec_y)
        turtle.left(90)
    turtle.end_fill()
def draw_star(center_x,center_y,radius):
    turtle.setpos(center_x,center_y)
    #find the peak of the five-pointed star
    pt1=turtle.pos()
    turtle.circle(-radius,72)
    pt2=turtle.pos()
    turtle.circle(-radius,72)
    pt3=turtle.pos()
    turtle.circle(-radius,72)
    pt4=turtle.pos()
    turtle.circle(-radius,72)
    pt5=turtle.pos()
    #draw the five-pointed star
    turtle.color('yellow','yellow')
    turtle.fill(True)
    turtle.goto(pt3)
    turtle.goto(pt1)
    turtle.goto(pt4)
    turtle.goto(pt2)
    turtle.goto(pt5)
    turtle.fill(False)
#start the project
turtle.speed(5)
turtle.penup()
#draw the rectangle
star_x=-320
star_y=-260
len_x=660
len_y=440
draw_rectangle(star_x,star_y,len_x,len_y)
#draw the big star
pice=660/30
big_center_x=star_x+5*pice
big_center_y=star_y+len_y-pice*5
turtle.goto(big_center_x,big_center_y)
turtle.left(90)
turtle.forward(pice*3)
turtle.right(90)
draw_star(turtle.xcor(),turtle.ycor(),pice*3)
#draw the small star
turtle.goto(star_x+10*pice,star_y+len_y-pice*2)
turtle.left(turtle.towards(big_center_x,big_center_y)-turtle.heading())
turtle.forward(pice)
turtle.right(90)
draw_star(turtle.xcor(),turtle.ycor(),pice)
#draw the second star
turtle.goto(star_x+pice*12,star_y+len_y-pice*4)
turtle.left(turtle.towards(big_center_x,big_center_y)-turtle.heading())
turtle.forward(pice)
turtle.right(90)
draw_star(turtle.xcor(),turtle.ycor(),pice)
#draw the third
turtle.goto(star_x+pice*12,star_y+len_y-7*pice)
turtle.left(turtle.towards(big_center_x,big_center_y)-turtle.heading())
turtle.forward(pice)
turtle.right(90)
draw_star(turtle.xcor(),turtle.ycor(),pice)
#draw the final
turtle.goto(star_x+pice*10,star_y+len_y-9*pice)
turtle.left(turtle.towards(big_center_x,big_center_y)-turtle.heading())
turtle.forward(pice)
turtle.right(90)
draw_star(turtle.xcor(),turtle.ycor(),pice)
turtle.ht()
time.sleep(3)
os._exit(1)结果：用Python的turtle模块画国旗用Python的turtle模块画国旗
