Python Syntax Portfolio Project: Medical Insurance

Hi! I would be very grateful for some feedback regarding my python syntax portfolio project.
I enjoyed this project - I returned to it after I completed the Data Scientist path as a refresher to help prepare for the final Data Scientist Portfolio Project, but wanted to stick to the topics covered in the Python Syntax modules to complete the project (with a bit of tkinter for fun!). There is plenty of scope for more and I hope to return to it again to work on those ‘Next Steps’!
