For both self development and guiding others, I’m looking for something like Hartl’s Rails tutorial (railstutorial_org/book).  Doing some research I’m seeing a thousand tutorials which cover some things well, and other wrong. Is there a Python/Flask equivalent to this book which follows a linear path and touches on front-end and back-end, tdd, containerizing, etc?  I can’t chart the path I’ve taken but do remember that fundamental course which shaped my early leaning path (t-sql with pencil and paper). Thanks for any help!
