Suit yourself really. maybe there's more training data for CRUD apps in python than C, but I don't think it's too hard to implement the fundamentals of a web app in any language if you're also using a web server. Most webapps aren't that popular therefore don't use that much computation anyways, so theres a point of diminishing returns on making your CRUD as efficient as scientifically possible. some prefer a managed runtime so that a bug causes EG python to crash instead of the consequences of a bug in native code, but that can be mitigated easily enough as well.
