def f_name(**var):
    """ #### Return the name of a keyword variable as a string.
        An alternative to using a list comprehension with function <v_name>
        that manipulates f-strings directly.

        Example:
        ```
            the_value = 'some_value'
            print(f_name(the_value=the_value))
        ```
