安装 pythonstartup 文件 [英] Installing pythonstartup file

问题描述

如何安装 pythonstartup 文件，以便它在 python myfile.py 之类的命令上运行?

How do I install the pythonstartup file so that it runs on command like python myfile.py?

我尝试将它安装到我的 Ubuntu 的 /home/myuser 目录中，但它说我没有足够的权限.此外，不同的地方交替说它应该全部大写或全部小写，并且在它之前有一个句点.Python 命令行指南似乎没有解释将文件放在哪里，或者如何更改哪个环境变量指向"它.

I tried to install it into my /home/myuser directory for Ubuntu, but it said that I had insufficient permissions. Furthermore, different places say alternately that it should be in all caps or in all lower case with a period before it. The Python command line guide does not seem to explain where to put the file, or how to change which environment variable to 'point' to it.

推荐答案

在你的 ~/.bashrc:

export PYTHONSTARTUP=$HOME/.pythonstartup

把你的python代码放在​​$HOME/.pythonstartup中，比如:

and put your python code in $HOME/.pythonstartup, like:

import rlcompleter
import readline

readline.parse_and_bind("tab: complete")

然后运行交互式shell:

Then run the interactive shell:

python

查看来自 PYTHONSTARTUP 的导入是否已处理.这仅适用于 python 交互模式.

See the imports from PYTHONSTARTUP are processed. This only works in python interactive mode.
