Assuming that the module file name filename.py

• The first step in the console input

import os
os.path.abspath('.\\filename.py')   #获得你要导入的模块的路径
'C:\\Users\\14469\\Desktop\\untitled\\filename.py'  

• The second step, just copy the path, and then added to sys.path

import sys
sys.path.append('C:\\Users\\14469\\Desktop\\untitled\\filename.py'  )

In this way it is guided into the module, but this is only temporary import module can only be effective in the current folder, the python's library path not find it , it is also very suitable for beginners
