Python: Flask – Generating a Static HTML Page

Whenever I need to quickly spin up a web application, Python’s Flask library is my go to tool. Recently, however, I found myself wanting to generate a static HTML page to upload to S3 and wondered if I could use it for that as well.
It’s actually not too tricky. If we’re in the scope of the app context then we have access to the template rendering that we’d normally use when serving the response to a web request.
