for loop over function that returns a tuple?

I have a function which is meant to return a tuple:
def get_metrics(server_status_json, metrics_to_extract, line_number):
return ((timestamp, "serverstatus", values, tags))
I also have:
def create_point(timestamp, metric_name, values, tags):
"measurement": _MEASUREMENT_PREFIX + metric_name,
I am calling get_metric in a for loop like so:
for metric_data in get_metrics(server_status_json, mmapv1_metrics, line_number):
I was hoping to use tuple unpacking to pass metric_data straight from get_metrics through to create_point.
However, in this case, metric_data only contains timestamp.
I suppose I could assign multiple variables like, and pass them through:
for timestamp, metric_name, value, tags in get_metrics(server_status_json, common_metrics, line_number):
However, that seems unnecessarily verbose, and I'm sure there's a simple way to do this with tuple unpacking?
