本文主要是介绍Python画国旗,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
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")
t.hideturtle()t.penup()
t.goto(0,-170/3)
t.pendown()
t.begin_fill()
t.forward(width / 2)
t.left(90)
t.forward(170)
t.left(90)
t.forward(width)
t.left(90)
t.forward(170)
t.end_fill()t.penup()
t.goto(0,height/2)
t.pendown()
t.begin_fill()
t.forward(height)
t.right(90)
t.forward(170)
t.right(90)
t.forward(height)
t.end_fill()t.pencolor("#d21034")
t.fillcolor("#d21034")t.penup()
t.goto(-170 / 3,height/2)
t.pendown()
t.begin_fill()
t.left(90)
t.forward(170/3)
t.left(90)
t.forward(height)
t.left(90)
t.forward(170/3)
t.end_fill()t.penup()
t.goto(-width/2,0)
t.pendown()
t.begin_fill()
t.forward(width)
t.left(90)
t.forward(170/3)
t.left(90)
t.forward(width)
t.left(90)
t.end_fill()turtle.mainloop()
