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. For example, 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. This is because :class:`int` is an immutable type, so the "

"reference to ``1`` can be reused. This behaviour depends on the "

"implementation used, so should not be relied upon, but is something to be "

"aware of when making use of object identity tests. However, after ``c = []; "

"d = []``, *c* and *d* are guaranteed to refer to two different, unique, "

"newly created empty lists. (Note that ``e = f = []`` assigns the *same* "

"object to both *e* and *f*.)"
