python添加tab键自动补全功能

时间：2023-12-24 09:23:31

默认python是没有tab键补全功能的：

>>> import tab

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

ImportError: No module named tab

>>>

　　

创建tab.py文件

# vi tab.py

添加以下内容：

#!/usr/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

　　

查看Python默认的模块存放地址

# python

Python 2.7.5 (default, Oct 11 2015, 17:47:16)

[GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2

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

>>> import sys

>>> sys.path

['', '/usr/lib64/python27.zip', '/usr/lib64/python2.7', '/usr/lib64/python2.7/plat-linux2', '/usr/lib64/python2.7/lib-tk', '/usr/lib64/python2.7/lib-old', '/usr/lib64/python2.7/lib-dynload', '/usr/lib64/python2.7/site-packages', '/usr/lib64/python2.7/site-packages/gtk-2.0', '/usr/lib/python2.7/site-packages']

>>>

　　

将tab.py文件拷贝到/usr/lib64/python2.7/

# cp tab.py  /usr/lib64/python2.7/

　　

这样就可以使用tab补全了：

>>> import tab

>>> import sys

>>> sys.

sys.__class__(              sys.exitfunc(

sys.__delattr__(            sys.flags

sys.__dict__                sys.float_info

sys.__displayhook__(        sys.float_repr_style

sys.__doc__                 sys.getcheckinterval(

sys.__excepthook__(         sys.getdefaultencoding(

sys.__format__(             sys.getdlopenflags(

sys.__getattribute__(       sys.getfilesystemencoding(
