为什么在文件路径中出现Unicode转义的SyntaxError? [英] Why do I get a SyntaxError for a Unicode escape in my file path?

问题描述

我要访问的文件夹称为python，位于我的桌面上.

The folder I want to get to is called python and is on my desktop.

当我尝试到达它时出现以下错误

I get the following error when I try to get to it

>>> os.chdir('C:\Users\expoperialed\Desktop\Python')
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

推荐答案

您需要使用 raw 字符串，将斜杠加倍或使用正斜杠:

You need to use a raw string, double your slashes or use forward slashes instead:

r'C:\Users\expoperialed\Desktop\Python'
'C:\\Users\\expoperialed\\Desktop\\Python'
'C:/Users/expoperialed/Desktop/Python'

在常规python字符串中，\U字符组合表示扩展的Unicode代码点转义.

In regular python strings, the \U character combination signals a extended Unicode codepoint escape.
