A recent message box version is the prompt_box module. It has two packages: alert and message. Message gives you greater control over the box, but takes longer to type up.
Example Alert code:
import prompt_box
prompt_box.alert('Hello') #This will output a dialog box with title Neutrino and the
#text you inputted. The buttons will be Yes, No and Cancel
Example Message code:
import prompt_box
prompt_box.message('Hello', 'Neutrino', 'You pressed yes', 'You pressed no', 'You
pressed cancel') #The first two are text and title, and the other three are what is
#printed when you press a certain button
