Flask คืออะไรและมีไว้ทำไม

Flask is a tiny, friendly way to build websites and APIs in Python. You will go from zero to a running web app, one small step at a time. 🙂

A web framework handles the boring plumbing of the web for you, so you write app logic instead of raw socket code.

Flask is a microframework: it ships a small, sharp core and lets you add only the pieces your project actually needs.

Unlike heavier frameworks, Flask does not force a database or folder layout on you. You stay in full control of how your app is shaped.

WSGI is the standard contract between Python web apps and servers. Flask speaks WSGI, so many servers can run it unchanged.

Under the hood Flask leans on Werkzeug for request handling and routing, giving you a solid, well-tested foundation.

Flask pairs with Jinja2 to turn templates into HTML pages, so you can mix Python data into your markup later on.

The core idea: a route connects a URL like /hello to one Python function that builds the response. You will write these soon.

Flask shines for small services, prototypes, and APIs. It scales up too, but its simplicity is what makes it perfect for learning.

Django bundles everything by default; Flask hands you a blank slate. You choose tools as you grow, which keeps your first app light.

Because Flask is pure Python, everything you already know about functions and dictionaries carries straight into your web app.
