def iif(condition,resultiftrue,resultiffalse):
if condition:return resultiftrue
else: return resultiffalse

#usage: furrycoat=iif(is_summer==True,”light coat”,”Heavy coat”)

Hi,
Not sure what you expect your code to do, but I think what you need is if with no else statement,
so if a%b ==0:
DoStuff()

This will do nothing otherwise.

>>> def iffy(a,b):
... for i in a:
... if i%b==0:
... print "Well Done!"

# you can try with this data:
a = range(5)
b = 2
iffy(a,b)

If you want this to stop as soon as any value of a is not diviible by b, add:
else: break
