Python海龟图形使用文本文件

Question

enter image description here I need help with Turtle graphics. I want the script to read my text file, and then draw a figure using the parameters in the text file. I think I almost got it, but gett error messages in the last part of the code. Can somebody please help me, thank you: :)

import turtle
turtle.pensize(4)
turtle.hideturtle()
turtle.speed(5)

with open ("tenge_eksempel_2.txt" , "r") as tekst:
lest_tekst = tekst.readlines()
Antall = 0
List_lengde = len(lest_tekst)
while List_lengde > Antall:
        if List_lengde < Antall:
        turtle.done()
    try:
        verdi = int(lest_tekst[Antall])
        if verdi < 0:
            turtle.penup()
        turtle.penup()
        turtle.right(verdi)
        Antall = Antall+1
        verdi = int(lest_tekst[Antall])
        turtle.pendown()
        if verdi < 0:
            turtle.penup()
        turtle.forward(verdi)
        Antall = Antall+1
        turtle.pendown()

turtle done

my text file looks like this: black 15 200 lgihtgrey 150 200 etc...

Answer 1

Given the text above: black 15 200 lightgray 150 200 black 300 200 lightgray 150 200 black 300 200 lightgray 150 200 black 300 200 lightgray 150 200. Assuming the black and gray are turtle pen colors and the 1st number angle and the 2nd pen motion, How would you separate the color(string) from the number? I tried the above code from the accepted answer but got no drawing in python turtle graphics. Just an empty blank turtle window.

Edit: I got no error messages, nor do I get a message saying process completed. I even left it to run for like 15-20 minutes just in case it was just slow.

Answer 2

Try this and see if it helps you figure out what's going on.

import turtle
turtle.pensize(4)
turtle.hideturtle()
turtle.speed(5)

with open ("tenge_eksempel_2.txt" , "r") as tekst:
    temp = tekst.readlines()
lest_tekst = temp [0].split ()

Antall = 1
List_lengde = len(lest_tekst)
while List_lengde > Antall:
    verdi = int(lest_tekst[Antall])
    if verdi > 0:
        turtle.right(verdi)
        Antall = Antall+1
        verdi = int(lest_tekst[Antall])
        print (verdi)
    if verdi > 0:
        turtle.forward(verdi)
    Antall = Antall+2

turtle.done ()

tenge_eksempel_2.txt is:

black 15 200 lightgray 150 200 black 300 200 lightgray 150 200 black 300 200 lightgray 150 200 black 300 200 lightgray 150 200 

Edit: On my system I get:
