1 查看python中的查找模块的路径
import sys sys.path [‘‘, ‘/usr/bin‘, ‘/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/lib64/python2.6/site-packages/gtk-2.0‘, ‘/usr/lib/python2.6/site-packages‘, ‘/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg-info‘, ‘/usr/lib/python2.6/site-packages/IPython/extensions‘]
2 查看一个模块的具体路径
方法1: 利用__file__属性
import MySQLdb MySQLdb.__file__ ‘/usr/lib64/python2.6/site-packages/MySQLdb/__init__.pyc‘
方法二:利用sys模块的modules方法
import sys sys.modules[‘MySQLdb‘] <module ‘MySQLdb‘ from ‘/usr/lib64/python2.6/site-packages/MySQLdb/__init__.pyc‘>
