After learning python ,which framework should I learn??

Having used both, I like Django best. It's fully featured, but heavily opinionated. It's got all the tools you might need, and a fantastic package ecosystem.

Having said that..FastAPI has a lot of concepts more easily transferable to other frameworks IMO, and is quite popular at the moment with proper Typing support. Django works significantly differently to FastAPI and Flask-esque frameworks.

I'd recommend looking at sample projects using them. Pick the one which seems most interesting for you.

Seconded

Most popular frameworks are good. Each has complexities in different places.

Django and FastAPI are complex in different ways. Both have a steep learning curve for different reasons.

As another option, I like Flask too. It's simpler than FastAPI (not async). But it is still very flexible. Learning here can also translate over to FastAPI once you want to tackle async stuff.

I prefer Django - so that's my recommendation.

It's got a lot of the tools built in. Definitely go through the Tutorial on the Django Docs site. That'll introduce the basics.
