You can use the currentframe of the inspect module. For example :
        
        >>> import inspect
        >>> def debug(string):
        ...     frame = inspect.currentframe(1)
        ...     print frame.f_code.co_name, string
        >>> def a_test_function():
        ...     debug("This is a message")
        >>> a_test_function()
        a_test_function This is a message

But please take note that this is not recommended. As stated in the
documentation of inspect.currentframe : "[t]his function should be used
for internal and specialized purposes only."
