I have read the official Flask documentation on Blueprints and even one or two blog posts on using them.
I’ve even used them in my web app, but I don’t completely understand what they are or how they fit into my app as a whole. How is it similar to an instance of my app but not quite? The documentation is comprehensive but I seek a layman explanation or an enlightening analogy to spark it for me. I was sufficiently perplexed when a colleague asked me to explain a Flask blueprint to them that I elected to ask here.
