It means you have the same name for your parameter as for your global
variable which is potentially confusing, so change the name of your
parameter.
Also you don't need the ** in front of DATA in the function definition.
Finally, you say it's working but you don't actually call your
function in your code. How are you exercising it? Did you just miss that
bit out or are you importing at the >>> prompt?
