python中的tab補齊

標籤：

首先需要知道python的讀取路徑

>>> import sys
>>> sys.path
[‘‘, ‘/usr/lib64/python26.zip‘, ‘/usr/lib64/python2.6‘, ‘/usr/lib64/python2.6/plat-linux2‘, ‘/usr/lib64/python2.6/lib-tk‘, ‘/usr/lib64/python2.6/lib-old‘, ‘/usr/lib64/python2.6/lib-dynload‘, ‘/usr/lib64/python2.6/site-packages‘, ‘/usr/lib/python2.6/site-packages‘]

 

可以看到python可以去這些地方讀取，我們把指令碼放在/usr/lib64/python2.6 即可

[[email protected] python2.6]# cat startup.py
#!/usr/bin/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

 

這樣做一個問題就是，你每次啟動python後，都需要手動匯入一下，比如

>>> import startup

 

可以在系統內容變數中，加入讀取路徑，這樣就免去了每次匯入的麻煩

[[email protected] python2.6]# cat ~/.bashrc 

export PYTHONSTARTUP=/usr/lib64/python2.6/startup.py

 

 

即可
