I don't know if there is an easier way, but this works for me:

import sys

def my_func():
    # Raise an exception so we can get a traceback
    try:
        raise ZeroDivisionError

    except ZeroDivisionError:
        # Get the traceback object
        tb = sys.exc_info()[2]

        # Get the stack frame object for this function
        f = tb.tb_frame

        # Get the code object from the frame object
        co = f.f_code

        # Get the module and function
        # names from the code object
        module_name = co.co_filename
        function_name = co.co_name

        print module_name, function_name

if __name__ == '__main__':

    my_func()


If you move the functionality into its own function, you can use the stack
frame object's f_back attribute to navigate to previous stack frame.
