You asked for someone to convince ou on getting the blood python but go back and read your own thread. It doesn't sound at all like you are at the stage to deal with a snake that is too aggressive. I am not saying tht you never will be but if you try to soon the experience can go really bad and potentially turn you away from the hobby all together. Keep looking ou for what you want. Don't just take something that doesn't suit you because it's a good deal.
I'm not saying there isn't a chance you could get the blood and have everything work out the way you want it. But there is a good chance it could go exactly the you said you were worried about in your first post. No need to take a risk like that at your stage. Get into the ion by more first so you may feel more comfortable with a snake like that.
My advice is don't take the blood python.
