How to lock .py file

[braveYug]

Thanks Metulburr for reply. I already tried Generating *.pyc file and making it bytecoded. My problem is that I am using *.py file in my C# code. As long as i specify file as *.py code works fine but as soon as i define it as *.pyc it gives me this error.

Error:
An exception of type 'System.ArgumentException' occurred in Microsoft.Scripting.dll but was not handled in user code

System.ArgumentException was unhandled by user code
  HResult=-2147024809

My C# code is like this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;




namespace WpfApp
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            func();
        }
        public void func()
        {
                        
            var ipy = Python.CreateRuntime();
            dynamic test = ipy.UseFile("pythonFunctions.pyc");
            lblText.Content=test.calcu(1,2,3,4,5);
            
        }
        
    }
}

It gives me error at line 37. I tried importing dll as reference too but that also didn't work.
Is there any way in C# to convert .pyc back to .py within code itself?
