Is my ball python underweight??

My girl is 3 feet long and 1.7 years old, and weighs 832g. I'm positive yours is at a good weight.

thanks you guys i taught she was underweight because i've seen some that are 3 feet and a year old and weight over 1000g i think they're just putting their snakes obese

thats perfect! here's a weight chart that some dude on here gave to me.. its a little far-fetched but its based on an average!
