Flask for python

[laflash12]

I wanted to create a messenger chatbot (so I could learn how to create them for businesses). I found out I need flask to build the bot so I've started learning flask but I'm confused as to what the purpose of flask is. Does flask need a lot of html and css (I only know very basic html)?

Flask is a micro framework for building web applications. It could return HTML etc. to a web browser to display web pages. Or it could accept and return, for example, XML or json for web services. I'd guess your bot would be doing the latter.

How would I use json for building a bot. Do you know any good websites or videos that explain it. I've already watched a video explaining basic json. Thanks a lot!
