Python tab键补全

    Python装完是不能用tab来补全的，我们需要将脚本放到python指定的目录下，可以使用sys.path来查看一下目录

    >>> import sys

    >>> sys.path

    ['', '/usr/local/python2.7.10/lib/python27.zip', '/usr/local/python2.7.10/lib/python2.7', '/usr/local/python2.7.10/lib/python2.7/plat-linux2', '/usr/local/python2.7.10/lib/python2.7/lib-tk', '/usr/local/python2.7.10/lib/python2.7/lib-old', '/usr/local/python2.7.10/lib/python2.7/lib-dynload', '/usr/local/python2.7.10/lib/python2.7/site-packages']



    一般我们会将这一类代码放在/usr/local/xxxxx/lib/python2.7/dist-packages目录下

    [root@python ~]# cd /usr/local/python2.7.10/lib/python2.7/site-packages


    [root@python site-packages]# vi tab.py

    #!/usr/bin/env python 

    # python startup 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


    [root@python site-packages]# python
