Parity Python

Inspired by the 90s PC game version of Snake, where he ate apples rather than the non-descript things in the mobile phone version
Normal Sudoku rules apply.
A black dot indicates that one of the touching digits is double the other.
A white dot indicates that the two touching digits differ by exactly one.
Not all dots are given.
The 9 apples each contain a unique digit.
Draw a Snake on the grid. It starts on the apple containing the 1 digit, and moves orthogonally, passing through the apples in order from 1 to 9, ending in the 9 space. It cannot pass through any dots.
The digits on the snake obey the following rules:
1] Each pair of digits contains one odd and one even digit
2] No digit on the snake may be greater than the greatest digit on an apple the snake has reached.

Solution code: The digits from the 8th to the 9th apple, inclusive (so beginning with the 8 and ending with the nine)

Added rules to the description that had been accidentally cut off when transferring from Sudokupad.

I struggled a bit with the break-in, but once I was past that I loved the flow of the rest of the puzzle! There were some fun deductions here.
