import os 
def rel(*x):
    return os.path.normcase(os.path.join(os.path.dirname(__file__), *x))

Sometimes (ex. django templates section at setting.py), a function expects an absolute path, but it's more practical when developing to refer it to the current file position in our code base. The rel function does exactly that.

Get an absolute from a path relative to the current file
