python 从文件内读取里面的字符串转化成列表绘制turtle

import turtle
from turtle import Turtle
def huizhi(str):
p=Turtle()
p.pensize(5)
p.speed(5)
for i in range(len(str)):
p.forward(str[i][0])
if str[i][1]==0:
p.left(str[i][2])
else:
p.right(str[i][2])
p.color(str[i][3],str[i][4],str[i][5])
turtle.done()
def main():
file=open(“data.txt”,“r”)
m=[]
for line in file:
m.append(list(map(float,line.split(","))))
print(m)
huizhi(m)
main()
