Which snakes can be housed together?

[Neal]

Like the title says, I am researching what will be my two newest pickups (KSB and a childrens python) and I keep comming across conflicting stories, some articles say that you can house multiple KSBs together and the same for childrens (obviously the two different species will be in different enclousures, I'm just asking in case I want to pick up a few more down the line), while others say its a bad idea. Is there any definitive answer as to which snakes (any not just talking about what I am picking up) can be housed together safely?

I wouldn't but that's me.
