python添加tab键自动补全功能

默认python是没有tab键补全功能的：

?

1 2 3 4 5

>>> 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：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

#!/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

?

1 2 3 4 5 6 7 8

# 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/

?

1	# cp tab.py  /usr/lib64/python2.7/

　　

这样就可以使用tab补全了：

?

1 2 3 4 5 6 7 8 9 10 11 12
