Matt,
There is also a nice thing you need to know about Python if you
already do not know. That is the fact that all empty collections bool
to False. This makes Truth testing easier.
>>> bool([])
False
>>> bool('')
False
>>> bool({})
False
>>> bool([1])
True
>>> bool([[]])
True
>>> bool(' ')
True
any empty collection, string, or 0 always bools to False.

a bunch of my code.
Thanks!
