python - 为什么这个海龟碰撞 if 语句有效？无法跟踪语句中的海龟位置。试图在 Pycharm 中跟踪，没有运气

Question

•   for count in range(15):
  
   turtle.forward(random.randint(0, 100))
  
   turtle.right(random.randint(0, 90))
  
   turtle.forward(random.randint(0, 50))
  
   turtle.circle(random.randint(0, 50))
  
   if turtle.pos() == turtle.pos():
     turtle.color("red")
     turtle.speed(0)
     #turtle.penup()
     #turtle.stamp()
     #turtle.hideturtle()
  

      *this code doesnt look right but I am a beginner myself my friend insists it makes the turtle turn red on collision. But how
  

  does
  > the if statement differentiate between 1 turtle and another? they ARE
  > all red at the end. How is that happening?
  

不知道如何使用 Pycharm 来跟踪 if 语句中询问了哪只海龟

Thanks in Advance I am learning fast.

Answer 1

你有第二只乌龟吗？如果你的另一只海龟被称为 Turtle2，那么它应该看起来像这样

if turtle.pos() == turtle2.pos():
   turtle.color("red")
   turtle.speed(0)
   #turtle.penup()
   #turtle.stamp()
   #turtle.hideturtle()

现在您正在查看海龟的位置是否与海龟的位置相同（相同的值）。这将永远是真的。
