One I've had to debug...

>>> text = 'abcdef'

>>> if text.find('abc'):
	print 'found it!'
# Nothing prints as bool(0) is False

>>> if text.find('bob'):
	print 'found it!'
found it!

Someone new who hasn't read the docs might try this, but then I guess it's not really a gotcha if they haven't bothered doing that.
