How can I get the function's caller?

[David]

Inside a function I need to get the function's caller's name. How can I get
it?

thanks in advance.

The "function caller", like most objects in Python, needn't actually
have a name. It could, for example, be a lambda stored as a list element.

What do you need this name for, just as a materr of interest? There are
ways of manipulating the stack frames, but they'll be slow and possibly
unreliable.

Check out the thread "__LINE__ and __FILE__ functionality in Python?"

I am writing a big (for me) program and it would be helpful to have a dummy
function like this:

def function_A_subfunction_B(self, ....)
dummy()

that display a standard message like this:

"Dummy: 'function_A_subfunction_B' in module 'module' is not defined yet"

Check also the warnings module (it will give you also line number
information for free).

One way would be to have dummy() raise an exception, which it catches.
Then use the traceback information to provide the information you want.

that's spelled

def function_A_subfunction_B(self, ....)
raise NotImplementedError

in Python.

You don't need to. Google is your friend. Google "caller name" in this
NG; it's that simple

Cheers,
