如何更改python中的默认工作目录 [英] How to change the default working directory in python

问题描述

我有一个关于直接在 python 上工作的默认值的快速问题.我目前正在使用 python 2.7.在这种情况下，默认直接工作的是 C:/Python27.我想将此永久更改为另一个目录.即使我们在shell上写下以下内容，默认工作目录也会自动回到原来的C:/Python27.

I have a quick question about the default working directly on python. I am currently using the python 2.7. In this case the default working directly is the C:/Python27. I want to change this permanently to another directory. Even if we write down following on shell, the default working directory will go back to the original C:/Python27 automatically.

import os

os.chdir('a path')

有谁知道如何将默认目录永久设置为关闭shell后保留目录的路径"?这与如何通过函数临时更改工作目录不同.
非常感谢您的帮助！！

Does any one know how to set up default directory permanently to "the path" which keeps the directory after the closing the shell? This is a different question from how to change working directory just by the function temporarily.
Thank you so much for your help!!

推荐答案

python 目录的工作目录是它启动的目录.如果从控制台(cmd.exe)我做 cd/some/dir 然后启动 python，它的工作目录将是 /some/dir.

The working directory of the python directory is the directory from which it was started. If from a console (cmd.exe) I do cd /some/dir and then start python, its working directory will be /some/dir.

如果您希望在给定目录中启动交互式控制台，您有一些选择:

If you want an interactive console started at a given directory you have some options:

• 使用快捷方式，您可以在属性选项卡中将其Start in 字段更改为指向您的目标目录.
• 改用 IPython，并添加一个 启动脚本 到默认配置文件，以便它始终从目标目录启动.IPython 是一种增强型交互工具，具有许多有用的功能.

• Using a shortcut, you can change its Start in field, in the properties tab, to point to your target directory.
• Use IPython instead, and add a startup script to the default profile so it always start at the target directory. IPython is an enhanced interactive with lots of useful features.

如果您从脚本运行并想切换到存储脚本的文件夹，您可以使用 os.cd(os.path.dirname(__file__)).

If you are running from a script and want to switch to the folder where you script is stored, you could use os.cd(os.path.dirname(__file__)).
