python import upper directory 1

python import upper directory

by 
import os,sys,inspect
currentdir = os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe())))
parentdir = os.path.dirname(currentdir)
sys.path.insert(0,parentdir) 

import mymodule

OR 

import os, sys

sys.path.insert(1, os.getcwd()) 
import variables

Here is what the above code is Doing:
1. It’s getting the current working directory (os.getcwd()) and adding it to the system path.
2. It’s importing the variables module.
