Python - Get path of root project structure

Question

I\'ve got a python project with a configuration file in the project root. The configuration file needs to be accessed in a few different files throughout the project.

Answer 1

Just an example: I want to run runio.py from within helper1.py

Project tree example:

myproject_root
- modules_dir/helpers_dir/helper1.py
- tools_dir/runio.py

Get project root:

import os
rootdir = os.path.dirname(os.path.realpath(__file__)).rsplit(os.sep, 2)[0]

Build path to script:

runme = os.path.join(rootdir, "tools_dir", "runio.py")
execfile(runme)
