朋友们，我很感激你们的帮助。我不是python专家，只是在帮我侄子做他的项目。
我们在更新屏幕时得到raise终结者错误。
我们在Google和StackOverflow上搜索了类似错误的查询- "raise Terminator error…"但似乎在得到答案方面没有进展。
代码如下:
import turtle
import time
import random
delay = 0.1
score = 0
high_score = 0
t=turtle.Screen()
t.title("Snake Xenzia")
t.bgcolor("skyblue")
t.setup(width=600, height=600)
t.tracer(0)
# Head of snake
head = turtle.Turtle()
head.shape("square")
head.color("white")
head.penup()
head.goto(0, 0)
head.direction = "Stop"
# Food
food = turtle.Turtle()
colors = random.choice(['red', 'green', 'blue'])
shapes = random.choice(['square', 'triangle', 'circle'])
food.speed(0)
food.shape(shapes)
food.color(colors)
food.penup()
food.goto(0, 100)
# Adding Segments
pen = turtle.Turtle()
pen.speed(0)
pen.shape("square")
pen.color("white")
pen.penup()
pen.hideturtle()
pen.goto(0, 250)
pen.write("Score : 0 High Score : 0", align="center",
font=("candara", 24, "bold"))

任何帮助都会很感激。谢谢。
我无法重现您描述的错误。然而，有一些问题的代码，一旦解决可能解决您的问题。
最明显的问题是while True:循环，它在事件驱动的环境中没有位置，比如turtle，以及从未到达的mainloop()调用。我们应该用ontimer()事件来代替。
另一个问题是您的"stop"和"Stop"令牌有两个不同的字母案例。这不是一个迫在眉睫的问题，但很容易成为一个问题。
在没有绘制任何内容的段上调用segment.clear()。这看起来像一个副本&在之前的循环中粘贴segments.clear()的工件
您在不实际使用colors和shapes时设置它们。你的墙碰撞和身体碰撞代码几乎是相同的,可以合并成一个。
下面是我对你的代码的修改。看看这些改变是否对你有意义，是否能解决你的问题:

请注意，一旦你关闭了tracer()，调用speed()方法什么也不做，因为我们正在运行。
