Why? Of what value would that be?
Note that I'm not merely being obstructionist here. What you're asking
here is not something that a Python programmer would normally ask. The
compiled code in a function, for example, exists as an object without a
name. That unnamed object can be bound to one or more function names, but
the code doesn't know that. Example:
def one():
print( "Here's one" )
two = one
That creates one function object, bound to two names. What name would you
expect to grab inside the function?
Even more obscure:
two = lamba : "one"
one = two
Which one of these is the "name" of the function?

It is of quite value to me.
Because I have this situation:
I have used a dictionary with "function_name":value pair in the top of the
code. Now when some function is called, I need to print the value assigned to its name in
the dictionary (the functions are defined after the dictionary). Now there is only one
bad way-around for me: I need to hard-code the name in the function like this:
def function_name():
print(dict_name.get("function_name"))
but ofcourse it is a bad thing to do because I have a lot of this type of
functions. It would be better if I can can use the same code for all of them,
because they are all essentially doing the same thing.
Now, for your questions:
If i call one() and two() respectively, i would like to see "one" and "two".
I dont have much knowledge of lambda functions, neither am i going to use them,
so that's something I cant answer.
How about defining a function that prints value and then calls a function?
def call(func_name):
print(mydict[func_name])
globals()[func_name]()
You could also define a custom class that does the same thing on attribute
lookup and do something like Call.func_name() .
