You mean like a ternary operation?

 >>> True and 1 or 0
1
 >>> False and 1 or 0
0

This of course depends on the 'true' result also being true.. it fails 
if it is false...

if that's not what you mean, then maybe this is what you want

if not var==A or not var==B or not var==C:
     # do something
