我的代码最简单是

import os
from turtle import Turtle,Screen
print(os.getcwd())
os.chdir('C:\Users\Travi\Downloads')
print(os.getcwd())
screen.register_shape("Crawfish_attack.gif")
Turtle.shape("Crawfish_attack.gif")

Answer 1

这样试试：

import os
from turtle import Turtle, Screen

print(os.getcwd())
os.chdir('C:\Users\Travi\Downloads')
print(os.getcwd())

screen = Screen()
screen.register_shape('Crawfish_attack.gif')

crawfish = Turtle()
crawfish.shape('Crawfish_attack.gif')

screen.exitonclick()

您正在对尚未创建的实例调用方法，并在 class 上调用实例方法。如果以上方法适合你，你应该也可以结合这些：

crawfish = Turtle()
crawfish.shape('Crawfish_attack.gif')

进入：

crawfish = Turtle('Crawfish_attack.gif')
