How do I return a Python script result from C# without printing?

This sort of question has been asked before in varying degrees, but I feel it has not been answered in a concise way and so I ask it again.

I want to run a script in Python. Let's say it's this:

def func1():
    list = [1,2,3,4,5]
    return list

Which gets the empty result.when putting print statement its return value to c#.but I want a result without printing in python. My actual code result is very big.so it takes time.

Okay, so how do I run this in C#?

This is what I have now:

   var process = new Process () {
  StartInfo = new ProcessStartInfo {
  FileName = "python",
  Arguments = "-u /home/varun/Desktop/data.py",
  RedirectStandardOutput = true,
  RedirectStandardError = true,
  UseShellExecute = false,
  CreateNoWindow = true,
  }
};
process.Start ();
string output = process.StandardOutput.ReadToEnd ();
string error = process.StandardError.ReadToEnd ();
process.WaitForExit ();
if (string.IsNullOrEmpty (error)) { return output; } else {
  Console.WriteLine (error);
  return error;
}
