Passing arguments to function - (The fundamentals are confusing me)

Thanks everyone. I understand now. Everything is a reference, all
that matters is whether I can go inside the "cubbyhole" and change
something. Immutables don't allow this.
So what if I do want to share a boolean variable like so:
<code>
sharedbool=True
class cls1:pass
cl=cls1()
cl.sharedbool1=sharedbool
sharedbool=False
>>cl.sharedbool1
True #but I wanted false!
</code>
My guess having read this threat would be to make a simple wrapper
class for a boolean so I'm changing something inside the object
instead of reassigning it?
<code>
class bigbool:
/t def __init__(self,tf):
/t/t self.val=tf
/t def setval(self,tf):
/t/t self.val=tf
</code>
Is there an easier way?
