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.
