We learned about HTTP methods, serving web pages, and dynamic routes. Volumetric flask is used for preparing liquids with volumes of high precision. a bottle, usually of glass, having a rounded body and a narrow neck, used especially in laboratory experimentation. It can be used to build a custom software framework on top of it and supports Python 2.7 and 3.5 and later.[13][14]. It also keeps the liquid at the same temparature over a number of hours. The Flask starter exposes a short-list with data structures used globally across the app: current_user object. non-web python apps - free experience More lightweight apps, but it will not give you a performance boost (you will save only a couple of CPU loops), most issues come with heavy and joined DB requests without indexes which could happen on both frameworks when you don't analyze the performance It is a WSGI web app framework. 1. It has no database abstraction layer, form validation, or any other components where pre-existing third-party libraries provide common functions.
