Here are the prototypes for the two main functions behind curses and urwid, respectively. I found the differences to be interesting, prototype size being the most apparent.
Previously, I posted a video by Sean Zicari that had a lot of helpful information in it. When somebody asked about the differences between them, he replied that they have very different ways of thinking, but urwid will ultimately do more for you. I think that makes a lot of sense when you look at what information each library expects to be given when called.
