What Do I Need to Make this Project Work?

Hello!

I am starting my Code Academy learnings with a specific goal: The company I work for has a newsletter. I want to build a tool where editors could put in a test subject line and it would analyze the prior data to spit out a hypothetical open rate for that subject line. Is this possible with python? What aspects would be most important to pay attention to during the Code Academy courses? What program would I need to build that in. Thank you!
