msgid ""
":dfn:`Objects` are Python's abstraction for data. All data in a Python "
"program is represented by objects or by relations between objects. (In a "
"sense, and in conformance to Von Neumann's model of a \"stored program "
"computer\", code is also represented by objects.)"
msgstr ""
#: ../../reference/datamodel.rst:35
msgid ""
"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."
msgstr ""
#: ../../reference/datamodel.rst:42
msgid "For CPython, ``id(x)`` is the memory address where ``x`` is stored."
msgstr ""
#: ../../reference/datamodel.rst:44
msgid ""
"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). Like its identity, an object's :dfn:`type` is also "
"unchangeable. [#]_"
msgstr ""
#: ../../reference/datamodel.rst:50
msgid ""
"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."
msgstr ""
#: ../../reference/datamodel.rst:65
msgid ""
"Objects are never explicitly destroyed; however, when they become "
"unreachable they may be garbage-collected. An implementation is allowed to "
"postpone garbage collection or omit it altogether --- it is a matter of "
"implementation quality how garbage collection is implemented, as long as no "
"objects are collected that are still reachable."
msgstr ""
#: ../../reference/datamodel.rst:73
msgid ""
"CPython currently uses a reference-counting scheme with (optional) delayed "
"detection of cyclically linked garbage, which collects most objects as soon "
"as they become unreachable, but is not guaranteed to collect garbage "
"containing circular references. See the documentation of the :mod:`gc` "
"module for information on controlling the collection of cyclic garbage. "
"Other implementations act differently and CPython may change. Do not depend "
"on immediate finalization of objects when they become unreachable (so you "
"should always close files explicitly)."
msgstr ""
#: ../../reference/datamodel.rst:82
msgid ""
"Note that the use of the implementation's tracing or debugging facilities "
"may keep objects alive that would normally be collectable. Also note that "
"catching an exception with a ':keyword:`try`...\\ :keyword:`except`' "
"statement may keep objects alive."
msgstr ""
#: ../../reference/datamodel.rst:87
msgid ""
"Some objects contain references to \"external\" resources such as open files "
"or windows. It is understood that these resources are freed when the object "
"is garbage-collected, but since garbage collection is not guaranteed to "
"happen, such objects also provide an explicit way to release the external "
"resource, usually a :meth:`close` method. Programs are strongly recommended "
"to explicitly close such objects. The ':keyword:`try`...\\ :keyword:"
"`finally`' statement and the ':keyword:`with`' statement provide convenient "
"ways to do this."
msgstr ""
#: ../../reference/datamodel.rst:97
msgid ""
"Some objects contain references to other objects; these are called "
"*containers*. Examples of containers are tuples, lists and dictionaries. "
"The references are part of a container's value. In most cases, when we talk "
"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 "
"container, only the identities of the immediately contained objects are "
"implied. So, if an immutable container (like a tuple) contains a reference "
"to a mutable object, its value changes if that mutable object is changed."
msgstr ""
#: ../../reference/datamodel.rst:106
msgid ""
"Types affect almost all aspects of object behavior. Even the importance of "
"object identity is affected in some sense: for immutable types, operations "
"that compute new values may actually return a reference to any existing "
"object with the same type and value, while for mutable objects this is not "
"allowed. E.g., after ``a = 1; b = 1``, ``a`` and ``b`` may or may not refer "
"to the same object with the value one, depending on the implementation, but "
"after ``c = []; d = []``, ``c`` and ``d`` are guaranteed to refer to two "
"different, unique, newly created empty lists. (Note that ``c = d = []`` "
"assigns the same object to both ``c`` and ``d``.)"

"Below is a list of the types that are built into Python. Extension modules "
"(written in C, Java, or other languages, depending on the implementation) "
"can define additional types. Future versions of Python may add types to the "
"type hierarchy (e.g., rational numbers, efficiently stored arrays of "
"integers, etc.), although such additions will often be provided via the "
"standard library instead."
