Many objects in python such as numbers like 10 or strings are immutable;
they can never be altered once called into existance.  When you assign
to a variable, you are binding the variable name to an object.  So if
you later took your x variable and re-assigned it to value 11, the id of
x would change to reflect this new object 11.

If you could find the memory address in your example where 10 is stored,
and then modified it, you could mess up a lot of things because the
interpreter is free to optimize and to use the same 10 object every
places where 10 is assigned to a variable.
