It looks like Uttar Pradesh (
http://mapsofindia.com/maps/uttarpradesh/location.htm ) is within the range of Asian rock python (
Python molurus ) according to the posts by Wattso (thanks mate). The
Python molurus complex includes the burmese python which is certainly big enough to take a human.
Still, two parts of the story seem suss,
1/ the python dragged away the girl (but her sister proberly didn't stick around to check)
2/ they couldn't find the snake - but the article states that they tried digging up the snake, but a python after a large meal would proberly be somewhere sunny.
It is also winter in that part of the world - would the pythons be feeding now?
Another possiblitly is that I am too old and cynical for my own good
