If the method of the request is ‘POST’, we return a greeting https://remotemode.net/ with the username from the form. Then, create __init__.py in the folders, which are to be used as modules. Overall, this makes the management of configurations for different deployment environments more flexible and easy.

The microframework simply refers to the fact that Flask aims to keep the core of its framework small but highly extensible.
