Normal Sudoku rules apply.
Additionally, the digits 1 and 9 may not be within a king's move of themselves or each other.
The final grid will contain a 1-width python, beginning and ending at the given 9s. Each 1 and 9 in the grid will be part of the python. The python may not touch itself orthogonally or diagonally.
Numbers in purple squares show how many of its 8 surrounding squares are python. Purple squares cannot be python. All possible purple squares are given.

This was lovely. Thanks for setting such a fun and interesting puzzle. I feel like this ruleset could produce additional puzzles... I may try my hand at one if you don't mind!!

A puzzle with this many rules usually suffers from the rules acting independently. But not with this puzzle--the logic works together really nicely :) If anyone is put off by the length of the ruleset or the low difficulty rating, please give this puzzle a try. It's really elegant and fun.

My first snake finished, just between difficult and easy for me! Thanks for your time making it :-)

Sehr hübsch und angenehm leicht :-), obwohl ich dreimal neu anfangen musste :-(.
