The del statement doesn't actually free memory. It just removes the binding from the corresponding namespace. So in your first example, my_string cannot be used after the deletion. Of course, if the string referenced by my_string was referenced by some other name then it will still stay in memory.
And even if it wasn't, and as such ends up being garbage-collected, this doesn't mean the allocated memory will go back to the system.
