":dfn:`Objects` are Python's abstraction for data.  All data in a Python "

"Every object has an identity, a type and a value.  An object's *identity* "
"never changes once it has been created; you may think of it as the object's "
"address in memory.  The ':keyword:`is`' operator compares the identity of "
"two objects; the :func:`id` function returns an integer representing its "
"identity (currently implemented as its address). An object's :dfn:`type` is "
"also unchangeable. [#]_ An object's type determines the operations that the "
"object supports (e.g., \"does it have a length?\") and also defines the "
"possible values for objects of that type.  The :func:`type` function returns "
"an object's type (which is an object itself).  The *value* of some objects "
"can change.  Objects whose value can change are said to be *mutable*; "
"objects whose value is unchangeable once they are created are called "
"*immutable*. (The value of an immutable container object that contains a "
"reference to a mutable object can change when the latter's value is changed; "
"however the container is still considered immutable, because the collection "
"of objects it contains cannot be changed.  So, immutability is not strictly "
"the same as having an unchangeable value, it is more subtle.) An object's "
"mutability is determined by its type; for instance, numbers, strings and "
"tuples are immutable, while dictionaries and lists are mutable."

"Some objects contain references to \"external\" resources such as open files "

"about the value of a container, we imply the values, not the identities of "
"the contained objects; however, when we talk about the mutability of a "
