Is there a snake that directly produces small snakes?

Snakes are oviparous and viviparous. Don't think viviparous is a patent for mammals. Such as blind snake, Agkistrodon halys, Agkistrodon halys, Bambusa bambusa, welding head, water snake, red snake, green slim snake, sea snake, etc.

However, the viviparous of snakes is different from that of mammals. Their fertilized eggs develop in the oviduct of the mother snake, but the nutrition needed for embryo development comes from the yolk of the fertilized egg, rather than absorbing maternal nutrition from the placenta through the umbilical cord. In fact, it is essentially different from mammals. Viviparous snake is called viviparous.
