前言

今天，我们来用turtle库来绘制国旗

一、美国国旗

国旗的形状是长方形;国旗的长宽之比为19:10，美国国旗由红、白、蓝三色组成;画面格局由两部分组成，旗的左上方蓝底上排列着50颗白色的星，6颗一排与5颗一排相间排列，共排9行;旗的其余部分是13道红白相间的条子，有7道红色横条以及6道白色横条。

import  turtle    
t = turtle.Pen()
b = turtle.Pen()   
t.speed(800)      
def ct(c):    t.color(c)     t.begin_fill()for i in range(2):t.forward(247)  t.right(90)t.forward(10)t.right(90)t.end_fill()
for i in range(14):  if i%2==1:   c ='white'else:c ='red'ct(c)t.right(90)t.forward(10)t.left(90)
t.up()     
t.home()
t.down()
for j in range(4):   t.color('blue')    t.begin_fill()t.forward(120)t.right(90)t.forward(70)t.right(90)t.end_fill()
def wjx():       b.color('white')b.begin_fill()for g in range(5):b.forward(6)b.left(144)b.end_fill()
def wjx6():     for l in range(6):b.up()b.forward(3)b.down()wjx()b.up()b.forward(18)b.down()
def wjx5():     for l in range(5):b.up()b.forward(10)b.down()wjx()b.up()b.forward(13)b.down()
b.right(90)    
b.forward(7)      
b.left(90)
for u in range(9):      if u%2 == 0:        wjx6()else:wjx5()     b.up()     b.home()b.right(90)b.forward((u+2)*7)b.left(90)b.down()
turtle.done()

二、奥兰群岛旗

奥兰群岛又称阿赫韦南马群岛(Ahvenanmaa)，是芬兰唯一的一个自治省，位于芬兰的西南沿海，由6500个小岛组成，岛上居民2.5万人，大多以瑞典语为母语。奥兰群岛的首府是玛丽港(Mairenhamn)。

import turtlewidth = 900
height = 600turtle.screensize(width,height,"#0053a5")
turtle.setup(width,height)
t = turtle.Turtle()
t.speed(10)t.pencolor("#ffce00")
t.fillcolor("#ffce00")
