在平时查看Python方法用到tab补全还是很方便的。
- 1. mac 平台 配置如下：
- mac是类Unix平台，需要在添加一条配置内容到bash_profile 中（默认是没有这个文件，可以新建一个放在宿主目录下面）
- 先新建一个tab.py的文件内容如下：
import rlcompleter,sys,readline if sys.platform == 'darwin' and sys.version_info[0] == 2:
readline.parse_and_bind("bind ^I rl_complete")
else:
readline.parse_and_bind("tab: complete")
- 查看当前系统的Python解释器路径

- sudo cp tab.py /Library/Python/2.7/site/packages/
- 将配置文件的信息写入到 ~/.bash_profile 中，如果文件存在则添加在文件内容后，如果不存在则新建该文件
- vi ~/.bash_profile 保存退出然后 source ~/.bash_profile (让该配置文件生效)
export PYTHONSTARTUP=/Library/Python/2.7/site-packages/tab.py

然后进入Python import tab 用tab则可以列出子方法如下

2.Ubuntu系统的配置文件和Mac有点不一样，同样写入一个tab.py文件到Python解释器路径下，其他的操作都不用,添加的代码如下:
sudo vi /usr/lib/python2./dist-packages/tab.py
import sys,readline,rlcompleter,atexit,os
readline.parse_and_bind('tab: complete')
histfile = os.path.join(os.environ['HOME'], '.pythonhistory')
try:
readline.read_history_file(histfile)
except IOError:
pass
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter
