许多人都知道 iPython 有很好的自动补全能力,但是就未必知道 python 也同样可以 Tab 键补全,
您可以在启动 python 后,执行下

代码如下:


import readline, rlcompleter; readline.parse_and_bind("tab: complete")

这就可以按 Tab 键补全了。

python 自启动
如果您嫌每次都要键入这东西麻烦的话,可以把上边这行写到 ~/.pythonstartup.py ,
再 ~/.bashrc 里加一个环境变量

export PYTHONSTARTUP=~/.pythonstartup.py这就会每次启动 python 都先执行了
