Get location of the .py source file

Say I have a python file in directory e like this: /a/b/c/d/e/file.py Under directory e I have a few folders I want to access but if file.py is executed from anywhere else rather than from folder e the relative path won't work for me. Also folder e could be located anywhere but always with the a set of sub folders so absolute path will not work. First, is there any function to get the absolute path in relation to the source files location? If not, any ideas how to sort this out? Grab the command line used and add the CWD together? My problem here is that this folder are being installed on 20 different machines and OS's and I want it to be as dynamic as possible with little configurations and "rules" where it has to be installed etc.
In Python +3.4 use of pathlib is more handy: from pathlib import Path source_path = Path(__file__).resolve() source_dir = source_path.parent
