Python環(huán)境中能使用tab鍵

[root@localhost ~]# cat /usr/lib/python2.7/startup.py #!/usr/bin/pythonimport rlcompleterimport readlineimport atexitimport os# http://stackoverflow.com/questions/7116038/python-tab-completion-mac-osx-10-7-lionif'libedit'in readline.__doc__:	readline.parse_and_bind('bind ^I rl_complete')else:	readline.parse_and_bind('tab: complete')histfile = os.path.join(os.environ['HOME'],'.pyhist')try:	readline.read_history_file(histfile)except IOError:	passatexit.register(readline.write_history_file, histfile)del readline, rlcompleter, histfile, os

修改~/.vimrc文件，加入：set ts=4
