With pygame and pygame_textinput installed, couldn't get the second example to work

[ca-123321]

until adding "from pygame_textinput import *"

Happy to do a pull request, but I'm new-ish to python/pygame/git, so I might be missing something

People might be coming to pygame relatively new to python so it would be good to have examples fully working without any changes. On that note, it would be nice to have a bare-bones example of actually using input after hitting enter. A parse(text) method that just prints "Parsing: <textinput.value>" and then resets textinput.value to an empty string
