get current function name inside that function using python

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

import inspectdef whoami():     frame = inspect.currentframe()    return inspect.getframeinfo(frame).functiondef foo():    print(whoami())foo()

prints

whoami

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

For my logging purpose i want to log all the names of functions where my code is going

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 here2015-10-16 16:29:34,227 [INFO] whoami: Now I'm there2015-10-16 16:29:34,227 [INFO] foo: I'm back here again

For my logging purpose i want to log all the names of functions where my code is going

Have you considered decorators?

import functoolsdef logme(f):    @functools.wraps(f)    def wrapped(*args, **kwargs):        print(f.__name__)        return f(*args, **kwargs)    return wrapped@logmedef myfunction():    print("Doing some stuff")
