a_string is pointing to the above = string

now I change the value of = a_string

a_string =3D =22This string is different=22

I = understand that now a_string is pointing to a different string than it was = before, in a different location.

my question is = what happens to the original string?? Is it still in memory = somewhere, nameless?

Thanks in advance,
