[Zope] PHP style variable variables in Python?

[Michael LaPera]

Hello,

First of all I am new to Python and Zope coming from Java/PHP.

I am creating a simple Python script that displays a random image 
(image1, image2, image3....).
All I want to do do is generate a random number which is concatenated to 
the end of the context attribute similar to this example in PHP:

$randomNumber = ***some random number***
return context.{'image'.$randomNumber}

Is this possible (and easy) in Python?

Thanks,
Michael LaPera
