Python 中的tab补全

用Python时候没有TAB补全，挺痛苦的，以下是添加方法

<code>&lt;br&gt;</code>

1.准备一个Python脚本 cat &gt; tab.py &lt;&lt;EOF

#!/usr/local/bin/python

# python tab file 

import sys

import readline

import rlcompleter

import atexit

import os

# tab completion

readline.parse_and_bind('tab: complete')

# history file

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 

EOF

2.查看Python默认的模块存放位置

[root@victor python2.7]# python

Python 2.7.6 (default, Sep 17 2017, 04:41:33) 

[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

&gt;&gt;&gt; import sys

&gt;&gt;&gt; sys.path

['', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages']

3.拷贝到目录下

cp tab.py /usr/local/lib/python2.7

4.现在可以用了

[root@victor python]# cp tab.py /usr/local/lib/python2.7

[root@victor python]# python

&gt;&gt;&gt; import tab

&gt;&gt;&gt; sys.
