msgid "The import system"
msgstr ""

msgid ""
"Python code in one :term:`module` gains access to the code in another module "
"by the process of :term:`importing` it.  The :keyword:`import` statement is "
"the most common way of invoking the import machinery, but it is not the only "
"way.  Functions such as :func:`importlib.import_module` and built-in :func:"
"`__import__` can also be used to invoke the import machinery."
msgstr ""

msgid ""
"The :keyword:`import` statement combines two operations; it searches for the "
"named module, then it binds the results of that search to a name in the "
"local scope.  The search operation of the :keyword:`!import` statement is "
"defined as a call to the :func:`__import__` function, with the appropriate "
"arguments. The return value of :func:`__import__` is used to perform the "
"name binding operation of the :keyword:`!import` statement.  See the :"
"keyword:`!import` statement for the exact details of that name binding "
"operation."
msgstr ""

msgid ""
"A direct call to :func:`__import__` performs only the module search and, if "
"found, the module creation operation.  While certain side-effects may occur, "
"such as the importing of parent packages, and the updating of various caches "
"(including :data:`sys.modules`), only the :keyword:`import` statement "
"performs a name binding operation."
msgstr ""

msgid ""
"When an :keyword:`import` statement is executed, the standard builtin :func:"
"`__import__` function is called. Other mechanisms for invoking the import "
"system (such as :func:`importlib.import_module`) may choose to bypass :func:"
"`__import__` and use their own solutions to implement import semantics."
msgstr ""

msgid ""
"When a module is first imported, Python searches for the module and if "
"found, it creates a module object [#fnmo]_, initializing it.  If the named "
"module cannot be found, a :exc:`ModuleNotFoundError` is raised.  Python "
"implements various strategies to search for the named module when the import "
"machinery is invoked.  These strategies can be modified and extended by "
"using various hooks described in the sections below."
msgstr ""

msgid ""
"The import system has been updated to fully implement the second phase of :"
"pep:`302`. There is no longer any implicit import machinery - the full "
"import system is exposed through :data:`sys.meta_path`. In addition, native "
"namespace package support has been implemented (see :pep:`420`)."
msgstr ""

msgid ":mod:`importlib`"
msgstr ":mod:`importlib`"

msgid ""
"The :mod:`importlib` module provides a rich API for interacting with the "
"import system.  For example :func:`importlib.import_module` provides a "
"recommended, simpler API than built-in :func:`__import__` for invoking the "
"import machinery.  Refer to the :mod:`importlib` library documentation for "
"additional detail."
msgstr ""

msgid "Packages"
msgstr "Pakiety"

msgid ""
"Python has only one type of module object, and all modules are of this type, "
"regardless of whether the module is implemented in Python, C, or something "
"else.  To help organize modules and provide a naming hierarchy, Python has a "
"concept of :term:`packages <package>`."
msgstr ""

msgid ""
"You can think of packages as the directories on a file system and modules as "
"files within directories, but don't take this analogy too literally since "
"packages and modules need not originate from the file system.  For the "
"purposes of this documentation, we'll use this convenient analogy of "
"directories and files.  Like file system directories, packages are organized "
"hierarchically, and packages may themselves contain subpackages, as well as "
"regular modules."
msgstr ""

msgid ""
"It's important to keep in mind that all packages are modules, but not all "
"modules are packages.  Or put another way, packages are just a special kind "
"of module.  Specifically, any module that contains a ``__path__`` attribute "
"is considered a package."
msgstr ""

msgid ""
"All modules have a name.  Subpackage names are separated from their parent "
"package name by a dot, akin to Python's standard attribute access syntax.  "
"Thus you might have a package called :mod:`email`, which in turn has a "
"subpackage called :mod:`email.mime` and a module within that subpackage "
"called :mod:`email.mime.text`."
msgstr ""

msgid "Regular packages"
msgstr ""

msgid ""
"Python defines two types of packages, :term:`regular packages <regular "
"package>` and :term:`namespace packages <namespace package>`.  Regular "
"packages are traditional packages as they existed in Python 3.2 and earlier. "
"A regular package is typically implemented as a directory containing an "
"``__init__.py`` file.  When a regular package is imported, this ``__init__."
"py`` file is implicitly executed, and the objects it defines are bound to "
"names in the package's namespace.  The ``__init__.py`` file can contain the "
"same Python code that any other module can contain, and Python will add some "
"additional attributes to the module when it is imported."
msgstr ""

msgid ""
"For example, the following file system layout defines a top level ``parent`` "
"package with three subpackages::"
msgstr ""

msgid ""
"parent/\n"
"    __init__.py\n"
"    one/\n"
"        __init__.py\n"
"    two/\n"
"        __init__.py\n"
"    three/\n"
"        __init__.py"
msgstr ""

msgid ""
"Importing ``parent.one`` will implicitly execute ``parent/__init__.py`` and "
"``parent/one/__init__.py``.  Subsequent imports of ``parent.two`` or "
"``parent.three`` will execute ``parent/two/__init__.py`` and ``parent/three/"
"__init__.py`` respectively."
msgstr ""

msgid "Namespace packages"
msgstr ""

msgid ""
"A namespace package is a composite of various :term:`portions <portion>`, "
"where each portion contributes a subpackage to the parent package.  Portions "
"may reside in different locations on the file system.  Portions may also be "
"found in zip files, on the network, or anywhere else that Python searches "
"during import.  Namespace packages may or may not correspond directly to "
"objects on the file system; they may be virtual modules that have no "
"concrete representation."
msgstr ""

msgid ""
"Namespace packages do not use an ordinary list for their ``__path__`` "
"attribute. They instead use a custom iterable type which will automatically "
"perform a new search for package portions on the next import attempt within "
"that package if the path of their parent package (or :data:`sys.path` for a "
"top level package) changes."
msgstr ""

msgid ""
"With namespace packages, there is no ``parent/__init__.py`` file.  In fact, "
"there may be multiple ``parent`` directories found during import search, "
"where each one is provided by a different portion.  Thus ``parent/one`` may "
"not be physically located next to ``parent/two``.  In this case, Python will "
"create a namespace package for the top-level ``parent`` package whenever it "
"or one of its subpackages is imported."
msgstr ""

msgid "See also :pep:`420` for the namespace package specification."
msgstr ""

msgid "Searching"
msgstr ""

msgid ""
"To begin the search, Python needs the :term:`fully qualified <qualified "
"name>` name of the module (or package, but for the purposes of this "
"discussion, the difference is immaterial) being imported.  This name may "
"come from various arguments to the :keyword:`import` statement, or from the "
"parameters to the :func:`importlib.import_module` or :func:`__import__` "
"functions."
msgstr ""

msgid ""
"This name will be used in various phases of the import search, and it may be "
"the dotted path to a submodule, e.g. ``foo.bar.baz``.  In this case, Python "
"first tries to import ``foo``, then ``foo.bar``, and finally ``foo.bar."
"baz``. If any of the intermediate imports fail, a :exc:`ModuleNotFoundError` "
"is raised."
msgstr ""

msgid "The module cache"
msgstr ""

msgid ""
"The first place checked during import search is :data:`sys.modules`.  This "
"mapping serves as a cache of all modules that have been previously imported, "
"including the intermediate paths.  So if ``foo.bar.baz`` was previously "
"imported, :data:`sys.modules` will contain entries for ``foo``, ``foo.bar``, "
"and ``foo.bar.baz``.  Each key will have as its value the corresponding "
"module object."
msgstr ""

msgid ""
"During import, the module name is looked up in :data:`sys.modules` and if "
"present, the associated value is the module satisfying the import, and the "
"process completes.  However, if the value is ``None``, then a :exc:"
"`ModuleNotFoundError` is raised.  If the module name is missing, Python will "
"continue searching for the module."
msgstr ""

msgid ""
":data:`sys.modules` is writable.  Deleting a key may not destroy the "
"associated module (as other modules may hold references to it), but it will "
"invalidate the cache entry for the named module, causing Python to search "
"anew for the named module upon its next import. The key can also be assigned "
"to ``None``, forcing the next import of the module to result in a :exc:"
"`ModuleNotFoundError`."
msgstr ""

msgid ""
"Beware though, as if you keep a reference to the module object, invalidate "
"its cache entry in :data:`sys.modules`, and then re-import the named module, "
"the two module objects will *not* be the same. By contrast, :func:`importlib."
"reload` will reuse the *same* module object, and simply reinitialise the "
"module contents by rerunning the module's code."
msgstr ""

msgid "Finders and loaders"
msgstr ""

msgid ""
"If the named module is not found in :data:`sys.modules`, then Python's "
"import protocol is invoked to find and load the module.  This protocol "
"consists of two conceptual objects, :term:`finders <finder>` and :term:"
"`loaders <loader>`. A finder's job is to determine whether it can find the "
"named module using whatever strategy it knows about. Objects that implement "
"both of these interfaces are referred to as :term:`importers <importer>` - "
"they return themselves when they find that they can load the requested "
"module."
msgstr ""

msgid ""
"Python includes a number of default finders and importers.  The first one "
"knows how to locate built-in modules, and the second knows how to locate "
"frozen modules.  A third default finder searches an :term:`import path` for "
"modules.  The :term:`import path` is a list of locations that may name file "
"system paths or zip files.  It can also be extended to search for any "
"locatable resource, such as those identified by URLs."
msgstr ""

msgid ""
"The import machinery is extensible, so new finders can be added to extend "
"the range and scope of module searching."
msgstr ""

msgid ""
"Finders do not actually load modules.  If they can find the named module, "
"they return a :dfn:`module spec`, an encapsulation of the module's import-"
"related information, which the import machinery then uses when loading the "
"module."
msgstr ""

msgid ""
"The following sections describe the protocol for finders and loaders in more "
"detail, including how you can create and register new ones to extend the "
"import machinery."
msgstr ""

msgid ""
"In previous versions of Python, finders returned :term:`loaders <loader>` "
"directly, whereas now they return module specs which *contain* loaders. "
"Loaders are still used during import but have fewer responsibilities."
msgstr ""

msgid "Import hooks"
msgstr ""

msgid ""
"The import machinery is designed to be extensible; the primary mechanism for "
"this are the *import hooks*.  There are two types of import hooks: *meta "
"hooks* and *import path hooks*."
msgstr ""

msgid ""
"Meta hooks are called at the start of import processing, before any other "
"import processing has occurred, other than :data:`sys.modules` cache look "
"up. This allows meta hooks to override :data:`sys.path` processing, frozen "
"modules, or even built-in modules.  Meta hooks are registered by adding new "
"finder objects to :data:`sys.meta_path`, as described below."
msgstr ""

msgid ""
"Import path hooks are called as part of :data:`sys.path` (or ``package."
"__path__``) processing, at the point where their associated path item is "
"encountered.  Import path hooks are registered by adding new callables to :"
"data:`sys.path_hooks` as described below."
msgstr ""

msgid "The meta path"
msgstr ""

msgid ""
"When the named module is not found in :data:`sys.modules`, Python next "
"searches :data:`sys.meta_path`, which contains a list of meta path finder "
"objects.  These finders are queried in order to see if they know how to "
"handle the named module.  Meta path finders must implement a method called :"
"meth:`~importlib.abc.MetaPathFinder.find_spec` which takes three arguments: "
"a name, an import path, and (optionally) a target module.  The meta path "
"finder can use any strategy it wants to determine whether it can handle the "
"named module or not."
msgstr ""

msgid ""
"If the meta path finder knows how to handle the named module, it returns a "
"spec object.  If it cannot handle the named module, it returns ``None``.  "
"If :data:`sys.meta_path` processing reaches the end of its list without "
"returning a spec, then a :exc:`ModuleNotFoundError` is raised.  Any other "
"exceptions raised are simply propagated up, aborting the import process."
msgstr ""

msgid ""
"The :meth:`~importlib.abc.MetaPathFinder.find_spec` method of meta path "
"finders is called with two or three arguments.  The first is the fully "
"qualified name of the module being imported, for example ``foo.bar.baz``. "
"The second argument is the path entries to use for the module search.  For "
"top-level modules, the second argument is ``None``, but for submodules or "
"subpackages, the second argument is the value of the parent package's "
"``__path__`` attribute. If the appropriate ``__path__`` attribute cannot be "
"accessed, a :exc:`ModuleNotFoundError` is raised.  The third argument is an "
"existing module object that will be the target of loading later. The import "
"system passes in a target module only during reload."
msgstr ""

msgid ""
"The meta path may be traversed multiple times for a single import request. "
"For example, assuming none of the modules involved has already been cached, "
"importing ``foo.bar.baz`` will first perform a top level import, calling "
"``mpf.find_spec(\"foo\", None, None)`` on each meta path finder (``mpf``). "
"After ``foo`` has been imported, ``foo.bar`` will be imported by traversing "
"the meta path a second time, calling ``mpf.find_spec(\"foo.bar\", foo."
"__path__, None)``. Once ``foo.bar`` has been imported, the final traversal "
"will call ``mpf.find_spec(\"foo.bar.baz\", foo.bar.__path__, None)``."
msgstr ""

msgid ""
"Some meta path finders only support top level imports. These importers will "
"always return ``None`` when anything other than ``None`` is passed as the "
"second argument."
msgstr ""

msgid ""
"Python's default :data:`sys.meta_path` has three meta path finders, one that "
"knows how to import built-in modules, one that knows how to import frozen "
"modules, and one that knows how to import modules from an :term:`import "
"path` (i.e. the :term:`path based finder`)."
msgstr ""

msgid ""
"The :meth:`~importlib.abc.MetaPathFinder.find_spec` method of meta path "
"finders replaced :meth:`!find_module`, which is now deprecated.  While it "
"will continue to work without change, the import machinery will try it only "
"if the finder does not implement :meth:`~importlib.abc.MetaPathFinder."
"find_spec`."
msgstr ""

msgid ""
"Use of :meth:`!find_module` by the import system now raises :exc:"
"`ImportWarning`."
msgstr ""

msgid ""
":meth:`!find_module` has been removed. Use :meth:`~importlib.abc."
"MetaPathFinder.find_spec` instead."
msgstr ""

msgid "Loading"
msgstr ""

msgid ""
"If and when a module spec is found, the import machinery will use it (and "

"prevents unbounded recursion in the worst case and multiple loading in the "
"best."
msgstr ""

msgid ""
"If loading fails, the failing module -- and only the failing module -- gets "

msgstr ""

msgid ""

msgstr ""

msgid ""
"As mentioned previously, Python comes with several default meta path "
"finders. One of these, called the :term:`path based finder` (:class:"

"finding modules on the file system, handling special file types such as "
"Python source code (``.py`` files), Python byte code (``.pyc`` files) and "

"`zipimport` module in the standard library, the default path entry finders "
"also handle loading all of these file types (other than shared libraries) "
"from zipfiles."
