I prefer PHP 9/10 times, but I have come into situations where I've needed to use python (e.g. machine learning projects / websocket hosting)
At the end of the day, it depends on what you need. PHP is versatile, but cannot do everything, some things are easier done in python.

I would not personally host a website using python, I'd only ever allow a php front end to interface with the python backend.
