我的代码简化程度是

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

以这种方式尝试：

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()

您正在调用尚未创建的实例上的方法，并在类上调用实例方法。如果以上内容适合您，您还应该能够将这些结合起来：

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

成：

crawfish = Turtle('Crawfish_attack.gif')
