This repo folder is the corresponding Python 3 code to the Module 1 codelab. The tutorial STARTs with the Python 2 code in the Module 0 repo folder and leads developers through migrating away from App Engine's webapp2 web framework to Flask, culminating in the code in the mod1-flask folder. The codelab does not currently feature any bonus migration to Python 3, however doing so requires you to participate in the bundled services public preview program (see sidebar below) and which culminates in the code in this (mod1b-flask) folder. In the next (Module 2) codelab, users will migrate (the original Python 2 version of) this app from App Engine ndb to Cloud NDB for Datastore access.
