Python lettering?

I saw someone using python to do the lettering and numbers for a game, for like points, health, etc.
Can anyone help me out with that?

Well theres either blf inside python or BGUI. BGUI has pre-built display frames, buttons, text labels, text blocks, text input, progress/healthbars, image and video frames also. the buttons have built in on click functions and multiple themes/colors are possible by using a theme file.

ill be back around with a picture and code excerpts from my in progress gui.

Here are some screenshots of Bgui:

Version 0.06 of Bgui was just released yesterday, and you can grab it at the same site, just head to the downloads section.
