Python tab键补全

2023-01-31 01:01:46 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 completio

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
