python自定义模块
方法一：echo 'export PYTHONPATH='/root/pythondiy/' >> /root/.bashrc # 此目录为你模块的路径
# 然后使用sys模块查看环境变量
import sys
sys.path # 返回一个列表
['',
'/usr/local/bin',
/root/pythondiy',
'/usr/local/lib/python27.zip',
'/usr/local/lib/python2.7',
'/usr/local/lib/python2.7/plat-linux2',
'/usr/local/lib/python2.7/lib-tk',
'/usr/local/lib/python2.7/lib-old',
'/usr/local/lib/python2.7/lib-dynload',
'/usr/local/lib/python2.7/site-packages',
'/usr/local/lib/python2.7/site-packages/setuptools-28.8.0-py2.7.egg',
'/usr/local/lib/python2.7/site-packages/pip-9.0.1-py2.7.egg',
'/usr/local/lib/python2.7/site-packages/IPython/extensions',
'/root/.ipython']
方法二：
sys.path.append('/root/pythondiy') # 此方法临时有效
