Here's some very simple code that relies on the singleton nature of modules
that might be enough for your needs:
import os
_workingdir = None
def set():
global _workingdir
_workingdir = os.getcwd()
def get():
return _workingdir
At the start of your application, import workingdir and do a workingdir.set().
Then when you need to retrieve it, import it again and use workingdir.get():
a.py:
import workingdir
workingdir.set()
b.py:
import workingdir
print workingdir.get()
test.py:
import a
import b
You could also remove the need to call the .set() by implicitly assigning on
the first import:
if '_workingdir' not in locals():
_workingdir = os.getcwd()
But I like the explicitness.
