How to control Abaqus Command from Python code?

I want to run a lot of simulations to generate data sets. For that, I want to automate the analysis with Python. Python to open Abaqus command prompt with inputs supplied in the python code. 

For example, we can control the cmd from python as:

import os
os.system('cmd /c "abaqus cae noGUI=new_script.py"')

How do I do that to an Abaqus Command from Python?

I could have generated many models in one go using loops, but my model will be quite computationally heavy, so I want to run the new simulation for each model. When I use the same Abaqus file to run different analyses, it begins to get slower, hence the new model  ~> new file.

In a nutshell:

I want to open Abaqus Command and execute the lines I provide from the Python code. How to achieve this?
