So, you raise an exception, and Bob's your uncle:

def whocalled ():
    try:
        raise Exception ()
    except:
        list = traceback.extract_stack ()
        (file, line, func, None) = list [len (list) - 3]
        m = re.match ('.*/(.*)\.py', file)
        return m.group (1), func, line

def logmsg (level, txt):
    (file, func, None) = whocalled ()
    sys.stderr.write (file + "::" + func + ": " + txt + "\n")
