Diamond pythons are very special snakes. Not really any less hardy than other carpet pythons but paying attention to their set-ups and needs, I believe, are more crucial. Its debatable whether they actually need UV lighting but they seem to be more prone to brittle bone disorders later in life, that other pythons. They are sensitive to too high heat and humidity. But eh, bit of fresh, warm sunshine hasn't hurt anybody.
Do your homework. Research them - but don't just research carpet pythons in general. Also find stuff that relates just to the diamonds. If you think you can handle them, and look after them, as adults, then you're almost there.
