在mac上测试


ipython
In [4]: import sys 
In [5]: sys.path
Out[5]: 
[‘‘,
 ‘/usr/local/bin‘,
 ‘/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg‘,
 ‘/Library/Python/2.7/site-packages/mysql-0.0.1-py2.7.egg‘,

 ‘/Library/Python/2.7/site-packages/ipython-3.2.1-py2.7.egg/IPython/extensions‘,
 ‘/private/var/root/.ipython‘]


代码有了,我们还需要将脚本放到python指定的目录下,可以使用sys.path来查看一下

(linux服务器):一般我们会将这一类代码放在/usr/local/lib/python2.7/dist-packages目录下

(MAC存放在这个目录下)/Library/Python/2.7/site-packages

admindeMacBook-Air-62:site-packages admin$ vim tab.py 
#!/usr/bin/env 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


代码中就可以import tab了

In [11]: import tab
In [12]: sys.
sys.__class__(              sys.__setattr__(            sys.displayhook(            sys.getrecursionlimit(      sys.prefix
