In Python, *every* expression is a pointer. This fact is clearest when
you look a C-implemented Python functions (which have parameter types
and return types of PyObject*), or when using mutable types.
>>> class Spam:
... def __init__(self):
... self.foo = 0
...
>>> x = Spam()
>>> y = x
>>> y.foo = 17
>>> x.foo
17
Compare this to the C code:
typedef struct {int foo;} Spam;
...
Spam *x, *y;
...
y = x;
y->foo = 17;
printf("%d\n", x->foo);
