arcpy - Seeking Python script for creating .mxd files?

I am new to both ArcGIS and Python. My requirement is to automate the below MANUAL process:

1. Creating a layer in ArcGIS for Desktop. To put it in another words, creating an ArcMap document (.mxd).


2. Publishing the created ArcMap document (in Step 1) as a service to ArcGIS Server.

Currently we are doing this manually. I have come across scripts to automate step 2 using Python.

How can I automate step 1 and step 2?
