嗨 各位大大 我將程式碼改成這樣，有計算出結果了，可是會一直顯示出0，請問為甚麼會這樣?!

c#
class Program
    {
        static void Main(string[] args)
        {
            System.Timers.Timer timer = new System.Timers.Timer();
            timer.Enabled = true;
            timer.Interval = 3000;
            timer.Start();
            timer.Elapsed += new System.Timers.ElapsedEventHandler(test);

            Console.ReadKey();
        }
        private static void test(object source, ElapsedEventArgs e)
        {
           
            string line;

            System.IO.StreamReader file = new System.IO.StreamReader(@"C:\Users\wkj88\Desktop\teraterm.txt");
            while ((line = file.ReadToEnd()) != null)
            {
                
                ScriptRuntime pyRunTime = Python.CreateRuntime();
                dynamic obj = pyRunTime.UseFile(@"C:\Users\wkj88\hello.py");
                Console.Write(obj.welcome(line));
           

            }
            file.Close();
            Console.ReadKey();
        }
    }

python

def welcome(rms):
    a = rms.replace('\r\n','')
    results = list(map(int, a))

    return sum(results)
