Accessing Function Names from Within Functions

In Python, determining a function's name from within the function itself can be useful in situations where dynamic introspection is required.

The inspect module provides a convenient mechanism for obtaining information about a running program's code. Using inspect.stack(), we can access a list of frames representing the current call stack.

For a given function, the first frame in the stack list corresponds to the current function, while the second frame represents its caller. To access the function name, we can extract the third element of the first frame in the stack using inspect.stack()0.

Here's an example:

import inspect

def foo():
    print("my name is", inspect.stack()[0][3])

foo()

This code will print:

my name is foo
````
