Projecting data from one project onto the screen in another

I need your help on something related to my project. I am receiving data with C # using a kinect sensor. I also save this data I receive in the csv file. Using a web service with Python, I trained this data through machine learning and created a user interface with flask. I put textboxes for each data value in this interface. These 2 projects are now independent from each other. Normally, I look at the csv file and input that data and find results, but that's not what I want. When I run the sensor with c #, I want the data to come to these textboxes automatically. I guess I should have done this with API. But I don't know how I can do it. In short, I want to link the project I have written in these 2 different languages. My interface is available in the photo below. enter image description here Can you help me?
