What is the difference between a CORS mode request and a NO-CORS mode request and is there a way to make a CORS mode request in Python 3?

I am trying to make some fairly specific web scraping requests in Python 3.8

I have found that the problem in my code is that Python's Request module does not have an option for CORS Requests.

I have tested this in the JavaScript console in a web browser and it only works when CORS is enabled.

How do I make a CORS style request in Python 3.8?
