Flask was born in 2010 and is a lightweight web development framework written in Python by Armin ronacher (person's name).
Flask itself is equivalent to a core, which mainly implements routing distribution and template rendering functions , which are respectively integrated from Werkzeug and Jinja2 module packages, which are also the core of the Flask framework.
Although the core is streamlined, Flask provides a very good extension mechanism, and various requirements in development basically have corresponding official/third-party extensions that can be implemented, and it is even simple to implement it yourself.
