This doesn't do what was asked - it only works if test is defined in
the global namespace:

  def f():
      def test():
          "test function description"
          import traceback
          me = eval( traceback.extract_stack()[-1][2])
          print "DocString: %s  functionName: %s " % (me.__doc__, me.__name__)
  
      test()
  
  f()

Yields:

  Traceback (innermost last):
    File "fu.py", line 10, in ?
      f()
    File "fu.py", line 8, in f
      test()
    File "fu.py", line 5, in test
      me = eval( traceback.extract_stack()[-1][2])
    File "<string>", line 0, in ?
  NameError: test
