The ones that squeeze are constrictors and there are literally hundreds of different varieties. I would opt against a yellow Anadonda especially if you are a beginner at keeping snakes. I would also opt against one if you don't like getting bitten frequently. Getting tagged by a 10' snake is not really that fun not to mention when they real full size well into 15 - 20' range.
The one in the top pic used to bite me at least once every time I handled him but has mellowed out over the past month or so.
