How to print from Flask @app.route to python console

Question

I would like to simply print a \"hello world\" to the python console after /button is called by the user.

This is my naive approach:

@app.route(\'/button

I think the core issue with Flask is that stdout gets buffered. I was able to print with print('Hi', flush=True). You can also disable buffering by setting the PYTHONUNBUFFERED environment variable (to any non-empty string).
