Figure 10-7: The SmileyPop app is more like a game now that we’ve

added sound and a progress/feedback display.

The popping sound and progress display feedback have made

SmileyPop feel like a mobile app. As you’re popping smiley faces by

right-clicking, you can probably imagine tapping the smileys with

your finger to pop them on a mobile device. (To learn how to build

mobile apps, check out MIT’s App Inventor at http://appinventor

.mit.edu/.)

Putting It All Together

Here’s the complete code for SmileyPop, version 2.0. Remember to

keep the .py source code file, the CrazySmile.bmp image file, and

the pop.wav sound file all in the same folder.

At almost 90 lines, this app might be a bit too long to type by

hand. Go to http://www.nostarch.com/teachkids/ to download the

code, along with the sound and picture files.
