You guys are overcomplicating things. Frameworks generally force you to structure your code a certain way. Both frameworks and libraries provided added functionality so you don't have to code it. A library will not force you to structure your code a certain way. I also have no idea why I was downvoted, what I previously said is correct. The Werkzeug python library works as a wrapper. Without you declaring a __call__ function it's not going to work. It needs to call your code to wrap it. Any framework ORM's are an example of code you're calling.
