yeah, I’d do Flash first too, given your work. But Python makes me giddy and happy to code again – it’s been a while since I’ve had that.

If you’re actually doing it as indicated – i.e., pulling your function names from an array, as opposed to from user input or the database – I don’t see why it’s any more dangerous than your method.

I do need to learn Python though. However, due to the needs of my job, it’s lower on my list than Flash.

Yeah, fair pait. Eval’s dangerous though — given it’s dangerous, would you actually do it that way, or do you if/then/else?

Python’s culture is very much about clean and elegant code – I do love that I stop and think of the quality of my code a lot more when writing Python, because there’s the culture of Pythonic code… And, of course, import this.

Nice. In PHP I would solve it with the eval() function:

$lookup = array(‘Vendor1′ => ‘Vendor1′, ‘Vendor2′ => ‘Vendor2′, ‘Vendor3′ => ‘Vendor3′);

$foo = in_array($object_type, $lookup) ? eval($lookup[$object_type]) : false;
