Python has an operator call 'in', which will allow you to do what you're after.

"1 in (1,2,3)" will be true
"4 in (1,2,3)" will be false
"not 1 in (1,2,3)" will be false

So you'd be after something along the lines of:
not cellboard[0] in (cellboard[1], ...., celboard[8]).

This seems quite tedious to write, maybe you should consider something
along the lines of using slicing:

not celboard[0] in cellboard[1:8]

I hope i have given you enough tools to do what you're trying to do.
