Python Turtle模块绘制五星红旗

转载一篇《Python Turtle模块绘制五星红旗》供大家学习参考

python内置的绘图工具turtle模块

使用到Turtle方法的基本操作
turtle.forward(step):前进step个像素
turtle.back(step):后退step个像素
turtle.right():右转一个角度
turtle.left():左转一个角度
turtle.pencolor(“string”):画笔颜色
turtle.fillcolor(“string”):填充颜色
turtle.speed(int):运动速度

代码如下：

# 绘画
# 中国国旗 五星红旗
