If you don't know which Python-based Web framework you are using, and what is supported by your hosting, it's not clear why are you asking about Python at all. Yes, I think Python-based Web development is very valuable thing, but you need to have some motivation and at least have any idea of what is available at your hosting. (Do you have some hosting provider? did you talk to them or read their documentation?)
Look how many different Web frameworks based on Python are available, and, mind you, this least is not quite complete:

Perhaps the most known and used platform these days is Django:
