There is absolutely zero benefit to the snakes to be housed together, but there are many valid and legitimate reasons not to. Just do a quick forum search on cohabitation if you want to read all the reasons we say not to do it. Your snakes will do much better and ultimately be much healthier in their own enclosures.
To drama x, you really need to do some research and educate yourself before you start offering bad advice to new keepers who may not know the difference. Try looking up cohabitation yourself. It is especially a bad idea to house a male and female together. It is very possible that the snakes will breed before your female is ready, which could lead to her becoming egg bound and dying. But hey, your snakes not mine...
