源码：

1. #根据数据文件在窗口中动态路径绘制
2. import turtle 
3.  
4. def main():
5.     #设置窗口信息
6.     turtle.title('数据驱动的动态路径绘制')
7.     turtle.setup(800, 600, 0, 0)
8.     #设置画笔
9.     pen = turtle.Turtle()
10.     pen.color("red")
11.     pen.width(5)
12.     pen.shape("turtle")
13.     pen.speed(5)
14.     #读取文件
15.     result=[]
16.     file = open("data.txt","r")
17.     for line in file:
18.         result.append(list(map(float, line.split(','))))
19.     print(result)
20.     #动态绘制
21.     for i in range(len(result)):
22.         pen.color((result[i][3],result[i][4],result[i][5]))
23.         pen.forward(result[i][0])
24.         if result[i][1]:
25.             pen.rt(result[i][2])
26.         else:
27.             pen.lt(result[i][2])
28.     pen.goto(0,0)
29.  
30.  
31. if __name__ == '__main__':
32.     main()
