Solve the following python programming problem given the following code:
def get_formatter(config) : 
    formatter = api_formatter 
    if formatter ['statsd_metric_namespace'] : 
        def metric_namespace_formatter_wrapper(metric, value, timestamp, tags, hostname = None, device_name = None, metric_type = None, interval = None) : 
            metric_prefix = config ['statsd_metric_namespace'] 
            if (metric_prefix [(- 1)] != '.') : 
                metric_prefix += '.' 
return api_formatter ((metric_prefix + metric), value, timestamp, tags, hostname, device_name, metric_type, interval) 
formatter = metric_namespace_formatter_wrapper 
return formatter
