# Based on code sample at: http://www.marinamele.com/7-tips-to-time-python-scripts-and-control-memory-and-cpu-usage

# Decorator "fn_timer" which times a function and has argument "class-name".
def fn_timer(class_name):
    def _fn_timer(function):
        @wraps(function)
        def function_timer(*args, **kwargs):
            t0 = time.time()
            result = function(*args, **kwargs)
            t1 = time.time()
            print ("Total time running %s:: %s: %s seconds" %
                   (class_name, function.func_name, str(t1-t0))
                   )
            return result
        return function_timer
    return _fn_timer

# Using the "fn_timer" decorator and passing the function class name.
@fn_timer("class-name")
