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
Python 2.7.6 (v2.7.6:3a1db0d2747e, Nov 10 2013, 00:42:54) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path [‘‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/beautifulsoup4-4.4.1-py2.7.egg‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/requests-2.9.0-py2.7.egg‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/testkit_lite-3.1.14-py2.7.egg‘, ‘/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload‘, ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages‘, ‘/Library/Python/2.7/site-packages‘]
- 将刚刚新建好的tab.py 文件复制到解释器路径下面,一般放置在‘/Library/Python/2.7/site-packages/’目录下面
- 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
- 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)
然后进入Python import tab 用tab则可以列出子方法如下
Python 2.7.6 (v2.7.6:3a1db0d2747e, Nov 10 2013, 00:42:54) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import tab,sys >>> sys.

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/python2.7/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
