python-在特定目录下导入模块功能

方法1、在指定的目录下导入特定模块，（tab.py换行自动补齐语法模块）

[email protected]:~# ls /root/python/

csvt01  csvtpy  scan1.py  scanhostport.py  tab.py  tab.pyc  test.py

[email protected]:~# pwd

/root

[email protected]:~# python

Python 2.7.3 (default, Mar 14 2014, 11:57:14)

[GCC 4.7.2] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import os

>>> import sys

>>> sys.system('pwd')

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

AttributeError: 'module' object has no attribute 'system'

>>> os.system('pwd')

/root

>>> sys.path.append('/root/python/')

>>> import tab

>>>

方法2、可以直接在tab.py目录下直接导致

[email protected]:~/python# ls

csvt01  csvtpy  scan1.py  scanhostport.py  tab.py  tab.pyc  test.py

[email protected]:~/python# python
