I am trying to change the current working directory in python using os.chdir. I have the following code:
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：
import os
os.chdir("C:\Users\Josh\Desktop130216")
However, when I run it, it seems to change the directory, as it comes out with the following error message:
但是，当我运行它时，它似乎更改了目录，因为它出现以下错误消息：
Traceback (most recent call last):
File "C:\Users\Josh\Desktop\LapseBot 1.0\LapseBot.py", line 3, in <module>
os.chdir("C:\Users\Josh\Desktop130216")
WindowsError: [Error 2] The system cannot find the file specified
'C:\Users\Josh\Desktop\x8130216'
Can anyone help me?
谁能帮我？

Python is interpreting the \2013part of the path as the escape sequence\201, which maps to the character \x81, which is ü (and of course, C:\Users\Josh\Desktopü30216doesn't exist).
Python\2013将路径的一部分解释为转义序列\201，它映射到字符\x81ü （当然，C:\Users\Josh\Desktopü30216不存在）。
Use a raw string, to make sure that Python doesn't try to interpret anything following a \as an escape sequence.
使用原始字符串，以确保 Python 不会尝试将 a 后面的任何内容解释\为转义序列。
os.chdir(r"C:\Users\Josh\Desktop130216")

This should work -
这应该有效 -
os.chdir("C:\Users\Josh\Desktop\20130216")

You could also use os.path.join(documentation).
Example:
您也可以使用os.path.join（文档）。例子：
os.chdir(os.path.join('C:\Users\Josh\Desktop', '20130216'))
This is more elegant + it's compatible with different operating systems.
这更优雅+它与不同的操作系统兼容。

I have faced the same problem but you have to try:
我遇到了同样的问题，但你必须尝试：
os.chdir(c:\user\Josh\Desktop)
Use \\so maybe you should get your solution.

There are two to use os.chdir():
有两个可以使用os.chdir()：
If you are using raw string than use single backslash
\:os.chdir(r"C:\Users\Josh\Desktop\20130216")
如果您使用原始字符串而不是使用单个反斜杠
\：os.chdir(r"C:\Users\Josh\Desktop\20130216")
or
或者
If you are not using raw string than use double backslash
\\os.chdir("C:\Users\Josh\Desktop\20130216")
如果您不使用原始字符串，请使用双反斜杠
\\os.chdir("C:\Users\Josh\Desktop\20130216")
