The error has nothing to do with Zope, the algorithm is wrong. The loop is 
testing the contents of variable 'i' and you don't change 'i' inside it, so 
the loop never exits.
Try using "if i..." instead of "while i..."
Test your script standalone, using a python debugger like Pythonwin or 
IDLE, and once it works OK upload it into Zope.
