How to run python script from C#

Question

before i start... I realize that there were some issues like this one. But still,I can't find an answer that satisfies me. Down below, I placed my code:

private void run_cmd(string cmd, string args)
        {
            ProcessStartInfo start = new ProcessStartInfo();
            start.FileName = "cmd.exe";
            start.Arguments = $"C:/Users/Ola/AppData/Local/Programs/Python/Python38/python.exe 
{cmd} {args}"; // where these args come with parameters
            start.UseShellExecute = false;
            start.RedirectStandardOutput = true;
            start.WindowStyle = ProcessWindowStyle.Hidden;
            using (Process process = Process.Start(start))
            {
                using (StreamReader reader = process.StandardOutput)
                {
                    string result = reader.ReadToEnd();
                    Console.Write(result);
                }
            }
}

Can anyone tell me this class does not work properly? The output is just blank cmd window.
