OBJECT 没有名为 'goto' 的属性。文档清楚地表明它确实如此

OBJECT has no attribute called 'goto'. Documentation shows it clearly does

import turtle as t

screen= t.Screen()
screen.title('welcome to my game')
screen.bgcolor('black')

starting_position = [(-40,0),(-20,0),(-0,0)]
segments=[]

for position in starting_position:
  newsegment=t.Turtle('square')
  newsegment=t.color('white')
  newsegment.goto(position)
  segments.append

#Says object has no attribute called 'goto'.文档说应该。

当您重新分配 newsegment=t.color('white') 时,newsegment 不再是海龟对象。

for position in starting_position:
  newsegment=t.Turtle('square')
  newsegment.color('white')
  newsegment.goto(position)
