python os.chdir 正在修改传入的目录名 [英] Python os.chdir is modifying the passed directory name

问题描述

我正在尝试使用 os.chdir 更改 python 中的当前工作目录.我有以下代码:

I am trying to change the current working directory in python using os.chdir. I have the following code:

import os

os.chdir("C:UsersJoshDesktop20130216")

然而，当我运行它时，它似乎改变了目录，因为它出现了以下错误消息:

However, when I run it, it seems to change the directory, as it comes out with the following error message:

Traceback (most recent call last):
File "C:UsersJoshDesktopLapseBot 1.0LapseBot.py", line 3, in <module>
os.chdir("C:UsersJoshDesktop20130216")
WindowsError: [Error 2] The system cannot find the file specified
  'C:\Users\Josh\Desktopx8130216'

有人可以帮我吗?

推荐答案

Python 将路径的 2013 部分解释为 转义序列 201，它映射到字符 x81，即 ü(当然，C:UsersJoshDesktopü30216 不存在).

Python is interpreting the 2013 part of the path as the escape sequence 201, which maps to the character x81, which is ü (and of course, C:UsersJoshDesktopü30216 doesn't exist).

使用原始字符串，以确保 Python 不会尝试将 后面的任何内容解释为转义序列.

Use a raw string, to make sure that Python doesn't try to interpret anything following a as an escape sequence.

os.chdir(r"C:UsersJoshDesktop20130216")
