Can you provide a the Python code you requested given the following:
I am working on the file "Simple_HTTP_server.ipynb".
The first task is:
POST parameters handling
Example with custom POST handler follows. This server accept any url and process the POST request parameters. If you access this server with browser you will get simple HTML form that you can use to test POST request.
Can you write Python code for it?
