尝试从html(ajax)运行python脚本时出错

我是一个绝对的HTML初学者,我真的不知道我在做什么。我有一个由github托管的网站,我希望它在按下网站上的按钮时在我的计算机上执行python脚本。这是我目前的代码:

<!DOCTYPE html>
<html>
  <head> 
   <h1>Press The Button To Run The Python Script</h1>   
  </head>
  <body>
    <input type="button" id='script' name="scriptbutton" value=" Run Script " onclick="goPython()">

    <script src="http://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>

    <script>
        function goPython(){
            $.ajax({
              url: "MYSCRIPT.py",
             context: document.body
            }).done(function() {
             alert('finished python script');;
            });
        }
    </script>
  </body>
</html>

下面是我得到的错误:

Access to XMLHttpRequest at 'file:///C:/Users/Mihkel/Desktop/MYSCRIPT.py' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.

myscript.py和test.html文件位于同一目录中。我必须修改python脚本才能使其正常运行吗?对我来说,这个错误似乎是权限错误,是真的吗?
