python读取每行以逗号分隔的文本的的方法

import turtle as t
t.title(‘自动绘制轨迹‘)
t.setup(800,600,0,0)
t.pencolor("red")
t.pensize(5)

def tprint(a):
    t.pencolor(a[3],a[4],a[5])
    t.fd(a[0])
    if a[1]:
        t.right(a[2])
    else:
        t.left(a[2])

f = open("t.txt")
data= list()
for line in f:
    if len(line) == 1:
        break;
    data = line.replace("\n","") #去掉每一行的换行
    #print(data)
    data = eval(data)   #转换为元组
    #print(data)
    #print(data[0])
    tprint(data)　　　　#元组传参
f.close()

#以下为t.txt文本文件内容
