Actually, Eric's answer points the way if this is about logging:

You can adjust the formatter to log the function name:

import logging               

def whoami():
    logging.info("Now I'm there")

def foo():
    logging.info("I'm here")
    whoami()
    logging.info("I'm back here again")

logging.basicConfig(
    format="%(asctime)-15s [%(levelname)s] %(funcName)s: %(message)s",
    level=logging.INFO)
foo()

prints

2015-10-16 16:29:34,227 [INFO] foo: I'm here
2015-10-16 16:29:34,227 [INFO] whoami: Now I'm there
2015-10-16 16:29:34,227 [INFO] foo: I'm back here again

Answer 2

You probably want inspect.getframeinfo(frame).function:

import inspect

def whoami(): 
    frame = inspect.currentframe()
    return inspect.getframeinfo(frame).function

def foo():
    print(whoami())

foo()

prints

whoami

Have you considered decorators?

import functools
def logme(f):
    @functools.wraps(f)
    def wrapped(*args, **kwargs):
        print(f.__name__)
        return f(*args, **kwargs)
    return wrapped


@logme
def myfunction():
    print("Doing some stuff")

Call sys._getframe() to get a frame class instance. The f_code.co_name member holds the function name.

sys._getframe(0).f_code.co_name

Add a simple helper function func_name() to wrap the call

import sys

def func_name(): 
    return sys._getframe(1).f_code.co_name

def func1():
    print(func_name())

func1()  # prints 'func1'
