For loop with multiple if conditions - help for newbie on syntax

Terraform
1

I am currently stuck on the correct syntax structure (if what I am doing is even possible) - I would like to have single if condition evaluate from within a for loop using multiple OR’s

[for s in v: upper(s) if s != “Server1” || s != “Server3” ]

any tips on the correct use of || inside a for loop if item != or or

Thanks

It looks like my logic was flawed - I’m up and running - relief!

&& was required not ||
