A collection of (tested) snippets for using Flask
Each folder has a unique Flask app with the functionalities described in the folder name. The folder names are structured to provide a clear indication of the app's purpose and the functionalities it includes.
Each folder tries to include only one or two new functionalities as standalone applications, with the minimum code to perform such functionality.
To run an app, download it, go to the folder and then execute it in the console with the 'flask run --debug' flag. If no flag is required, the app.py or __ init __.py will specify how to run the app; otherwise, use this command from the command line in each directory:
