variable vs. object

[fl]

Hi,

I read several parts on line about Python that everything in Python is an 
object. Yes, it is a key difference with other languages. Then, I read a page
it says variables: global and local variable at:

I have a question that whether variables are objects?

For example,

a=10

'a' is an integer. Is it an object too?

Thanks,
