How to get the path where the current script you're running lives?#

 sys.path[0]
returns the path of the script that launched the python interpreter. If you can this script directly, it will return the path of the script. If the script however, was imported from another script, it will return the path of that script.

To import general.py 

import sys
sys.path.append('../somedir')
from general import somefunction

You may want to execute the script from any arbitrary path. 

import sys
sys.path.append(os.path.abspath(os.path.join(sys.path[0], '..', 'somedir')))
from general import somefunction
