HI all, I'm a bit stuck with how to work out boolian logic.
I'd like to say if A is not equal to B, C or D:
do something.
I've tried
if not var == A or B or C:
and various permutations but can't seem to get my head around it. I'm
pretty sure I need to know what is calulated first i.e the not or the
'OR/AND's
thanks, Marc. 6 1185
if a != b and a != c and a != d:
doStuff()
else:
doOtherStuff()
Cheers,
Drea

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

the not var==A or not var==B or not var==C was what I was after.I
was being too literal with my script and trying not (A or B or C)
which doesn't work.
Thanks for the help.

There's a number of ways of coding it. How about,
if not var in [A, B, C]:
#do stuff
