how can a function find the name by which it is called?

[Skaperen]

i am wanting to phrase the message in a certain context for this user base that is following some specific instructions to get specific results. these users are running commands (in the future, to use a GUI app) that constructs some Python code. these users are not coders and probably have no understanding of a traceback or the Python message. if the function can get the name that would simplify the task. otherwise i will need to add another argument in both the function and all makers of calling code.
