is vs in

[Skaperen]

i am doing testing for exactly the same as opposed to equivalent. this means using the is keyword for comparison. comparing 1 to True (for example) i want to be False. but i have cases in a new project where i need to test if a variable is (or is not) the same as any of a few values. the in keyword does not compare like is. it compares more like ==. is there a way to do an is-like comparison against a list (or tuple) of values? i tried this in the hope there was a way but that is not implemented.

if this is in that:
    print('yes')
else:
    print('no')

if this cannot be done, then that syntax is my suggested addition.
