Python Turtle导入本地图片遇Unicode转义错误，求排查问题所在

你的代码如下：

import turtle
screen=turtle.Screen()
opened_door="C:\Users\Roby&Gabry\Desktop\Monty Hall Paradox\opened_door.gif"
closed_door="C:\Users\Roby&Gabry\Desktop\Monty Hall Paradox\closed_door.gif"
screen.addshape(opened_door)
screen.addshape(closed_door)
t=turtle.Turtle()
t.shape(closed_door)

运行时触发的错误：

File "c:\Users\Roby&Gabry\Desktop\Monty Hall Paradox\Monty Hall.py", line 3
    opened_door="C:\Users\Roby&Gabry\Desktop\Monty Hall Paradox\opened_door.gif"
                                                                                ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

错误原因 #

Python中，字符串里的反斜杠\是转义字符，比如\n表示换行、\t表示制表符。当路径里出现\U时，Python会将其识别为Unicode转义序列的起始标记（完整格式是\UXXXXXXXX，需搭配8位十六进制数），但你的路径中\Users的\U后面没有符合要求的8位十六进制数，导致解码失败，触发SyntaxError。

解决方法 #

有三种常用方式修复路径字符串：

1. 使用原始字符串：在字符串前加r，让Python忽略所有转义序列，直接按字面解析字符串

import turtle
screen=turtle.Screen()
opened_door=r"C:\Users\Roby&Gabry\Desktop\Monty Hall Paradox\opened_door.gif"
closed_door=r"C:\Users\Roby&Gabry\Desktop\Monty Hall Paradox\closed_door.gif"
screen.addshape(opened_door)
screen.addshape(closed_door)
t=turtle.Turtle()
t.shape(closed_door)

2. 用双反斜杠转义：将每个\替换为\\，这样Python会把\\解析为单个反斜杠

import turtle
screen=turtle.Screen()
opened_door="C:\\Users\\Roby&Gabry\\Desktop\\Monty Hall Paradox\\opened_door.gif"
closed_door="C:\\Users\\Roby&Gabry\\Desktop\\Monty Hall Paradox\\closed_door.gif"
screen.addshape(opened_door)
screen.addshape(closed_door)
t=turtle.Turtle()
t.shape(closed_door)

3. 改用正斜杠：Python支持在路径中使用正斜杠/，无需转义，跨平台兼容性更好

import turtle
screen=turtle.Screen()
opened_door="C:/Users/Roby&Gabry/Desktop/Monty Hall Paradox/opened_door.gif"
closed_door="C:/Users/Roby&Gabry/Desktop/Monty Hall Paradox/closed_door.gif"
screen.addshape(opened_door)
screen.addshape(closed_door)
t=turtle.Turtle()
t.shape(closed_door)
