Ball python weight

[Cherry4812]

I've had my ball python, Tulio, for almost eleven months now. He's about a year old, 24 inches (give or take), and weighs 10 ounces. I got a scale specifically to weigh him and I was just wondering if that sounded like an appropriate weight for a ball python of his age. My friend has an older one that looks skinnier (you can see it's backbone protruding a lot) and she says mine looks overweight. I feed him one adult mouse once a week.
