New with a few questions

[sl1ther]

Hi there fellow python lovers.
I am new to this and thought a ball python would make a good starter snake because with my previous research they appear quite good.

Anyway now for my questions:
1.how big(average) do male ball pythons grow?
2.how big (average) do female ball pythons grow?
3.what size cage would i need for a full sized ball python?
4.are these snakes aggressive or are they quite laid back?
5.should i feed them live,prekilled or frozen?



thanks guys!
