Name of the function

[Olaf Meding]

I am looking for a way to get at the name of the function (while
executing code inside the function) without (!) knowing the name of
the function.

The code below works, but requires the name of the function. I am
looking for a way to do the same w/o specifying the name of the
function.

def olaf():
# requires name of the function
print olaf.__name__

# this does not work
print self.__name__

This seems to work:

def foo():
print inspect.current frame().f_code. co_name

Re: Name of the function

Is there a way to do this w/o importing another module?

Yes this is what I was looking for except the code below requires
importing module inspect.

Thanks much for your reply.

as does this ...
[color=blue][color=green][color=darkred]
>>> def f(): print f.func_name[/color][/color][/color]
....[color=blue][color=green][color=darkred]
>>> f()[/color][/color][/color]
f
.... as long as 'f' remains bound to that function in the same module, which
it will unless rebound either from within or without.

I'm afraid that there is no way, at least none I'm aware of (except for
Terry Reed suggestion, but I think it's not what you are looking for).

Why you don't want to import a module?

You could use sys instead, which is IIRC initialized at python start-up,
even though the name isn't put in the namespace until 'import sys'. So
strictly speaking, it's still importing, but there is no overhead.

sys._getframe() .f_code.co_name

I'll second that. I'll even ask why you want the original binding name of
the function. (When functions are first-class, the "name of the function"
becomes a bit meaningless.) What are you doing? We might be able to
suggest something better.
