python不同文件夹下的py文件调用

如果所示，login负责登录模块，省份新增需要调用登录模块login文件夹下的login.py

运行报错如下:
Traceback (most recent call last):
File “E:\Program Files\JetBrains\PyCharm 5.0.3\helpers\pycharm\utrunner.py”, line 121, in
modules = [loadSource(a[0])]
File “E:\Program Files\JetBrains\PyCharm 5.0.3\helpers\pycharm\utrunner.py”, line 41, in loadSource
module = imp.load_source(moduleName, fileName)
File “E:\python\miipsys_xy\province\province_add.py”, line 9, in
from login import login
ImportError: No module named login

解决方案：
在需要调用的py文件中，添加这两句即可：
import sys
sys.path.append(“..”)
