where am I ?

If you use the traceback module, you can peer back into the stack
regardless of whether there's an exception. I use a similar trick in a
logging routine:

  file, line, func, txt = traceback.extract_stack(None,2)[0]

That returns my current function's caller.

If you want your current function, try:

  file, line, func, txt = traceback.extract_stack(None,1)[0]

Luck,
