The Fullstack Python site has a page dedicated purely to Flask resources and tutorials. With links to the Mega Tutorial and many others – there seems to be an emphasis on guides that get you to make real projects.
Flask is a Python web framework – I haven’t yet tried it myself. After trying Django with the Django Girls tutorial (actually, I haven’t completed the last proper section yet – Django Forms). From what I’ve read about Flask it sounds like it is smaller and more “Pythonic”. For a definition of that word, the Secret Weblog recommends that you type
import this into a Python interpreter.. I just tried it and it works.
