I've been stuck on this for the past day, and I could've sworn I had everything right, I even checked this forum, but nothing I'm doing works.
It tells me that "by_three(1) resulted in an error: 'int' object is not callable".
My code is as follows:
cube = n**3
if n%3 == 0():
print "n is divisible by 3"
print "n is not"
I would greatly appreciate some help in figuring out what I did wrong!
