i read that 'is' compares if they are really the same object, but i don't that's it because then why does -5 return True? of course i could only use == to compare, but still, what am i missing here?
Rule of thumb: Never use 'is' with any kind of string or numeric object. 'is' is not a comparison operator. It checks for object identity.
You are getting the result because Python optimized small integers. See http://svn.python.org/projects/python/trunk/Objects/intobject.c Integers between -5 and +256 are singletons as are some other objects like strings with one element or empty tuples. You must not rely on the optimization.
