[pygame] Show text on screen for a limited time

[Dan Ross <dan@xxxxxxxxxxxxxxxxxx>]

Hi all- 

I have a spelling game that has the user spell a word that matches the
picture shown. 

When they press enter, the picture changes when correct and displays "Try
Again" if incorrect. 

I can't seem to figure out a way to have "Try Again" display for only a
set time. 

Any help would be appreciated. 

Thanks, 

Dan
