如何用python绘制五星红旗

使用turtle绘制五角星

源代码：​​​​​#五星红旗
import turtle
turtle.speed(0)
#背景颜色
turtle.bgcolor("red")
#填充颜色
turtle.color("yellow")
#抬笔画大五角星
turtle.up()
turtle.goto(-500,180)
turtle.down()
turtle.begin_fill()
# turtle.hideturtle()
for i in range(5):
turtle.forward(80)
turtle.left(72)
turtle.forward(80)
turtle.right(144)
turtle.end_fill()
#抬笔画小五角星
turtle.up()
turtle.goto(-300,270)
turtle.down()
turtle.left(20)
turtle.begin_fill()
for i in range(5):
turtle.forward(20)
turtle.left(72)
turtle.forward(20)
turtle.right(144)
turtle.end_fill()
#第二个小五角星
turtle.up()
turtle.goto(-220,180)
turtle.down()
turtle.left(40)
turtle.begin_fill()
for i in range(5):
turtle.forward(20)
turtle.left(72)
turtle.forward(20)
turtle.right(144)
turtle.end_fill()
#绘制第三个五角星
turtle.up()
turtle.goto(-200,70)
turtle.down()
turtle.left(60)
turtle.begin_fill()
for i in range(5):
turtle.forward(20)
turtle.left(75)
turtle.forward(20)
turtle.right(145)
turtle.end_fill()
#绘制第四个五角星
turtle.up()
turtle.goto(-240,10)
turtle.down()
turtle.left(60)
turtle.begin_fill()
for i in range(5):
turtle.forward(20)
turtle.left(72)
turtle.forward(20)
turtle.right(144)
turtle.end_fill()
turtle.hideturtle()
turtle.done()

由重复部分代码，我们可以使用函数节省步骤

#绘画红旗
#导入turtle
import turtle
#调制加快速度
turtle.speed(0)
#设置背景色为红色
turtle.bgcolor("red")
turtle.color("yellow")
#绘制五角星函数
#x:x的坐标轴值
#y:y的坐标轴值
#a:表示五角星的偏移度数
#b:表示五角星的长度
def hq(x,y,a,b):
turtle.up()
turtle.goto(x,y)
turtle.down()
turtle.left(a)
turtle.begin_fill()
for i in range(5):
turtle.forward(b)
turtle.left(72)
turtle.forward(b)
turtle.right(144)
turtle.end_fill()
hq(-500,180,0,80)
hq(-300,270,20,22)
hq(-220,180,40,22)
hq(-200,70,60,22)
hq(-240,20,80,22)
#隐藏箭头
turtle.hideturtle()
turtle.done()
