python设置环境变量

方法1:

当程序开发完毕，就可以添加到

'/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages'中

import sys,os
sys.path
['', '/Library/Frameworks/Python.framework/Versions/3.4/lib/python34.zip', '/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4', '/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/plat-darwin', '/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/lib-dynload', '/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages']

　就使用方法1

方法2:

import sys
import os
pre_path = os.path.abspath('/Users/Alan/desktop/Alanproject/day5/my_pj')
#设置环境变量，把该主目录添加到sys.path里.文件退出则无效，所以写死在这个主文件
sys.path.append(pre_path)
from backend.logic import view,handle

view.home()
view.movie()
handle.cal()
