This makes readingresources included in packages easier, with more stable and consistentsemantics.加载器想要支持资源读取应该实现一个由 importlib.abc.ResourceReader 指定的get_resource_reader(fullname) 方法。The following types are defined.importlib.resources.Package¶The Package type is defined as Union[str, ModuleType]. This meansthat where the function describes accepting a Package, you can pass ineither a string or a module. Module objects must have a resolvable__spec__.submodule_search_locations that is not None.importlib.resources.Resource¶This type describes the resource names passed into the various functionsin this package. This is defined as Union[str, os.PathLike].The following functions are available.importlib.resources.files(package)¶Returns an importlib.resources.abc.Traversable objectrepresenting the resource container for the package (think directory)and its resources (think files). A Traversable may contain othercontainers (think subdirectories).package is either a name or a module object which conforms to thePackage requirements.3.9 新版功能.importlib.resources.open_binary(package, resource)¶Open for binary reading the resource within package.package is either a name or a module object which conforms to thePackage requirements. resource is the name of the resource to openwithin package; it may not contain path separators and it may not havesub-resources (i.e. it cannot be a directory). This function returns atyping.BinaryIO instance, a binary I/O stream open for reading.importlib.resources.open_text(package, resource, encodingutf-8, errorsstrict)¶Open for text reading the resource within package. By default, theresource is opened for reading as UTF-8.package is either a name or a module object which conforms to thePackage requirements. resource is the name of the resource to openwithin package; it may not contain path separators and it may not havesub-resources (i.e. it cannot be a directory). encoding and errorshave the same meaning as with built-in open().This function returns a typing.TextIO instance, a text I/O stream openfor reading.importlib.resources.read_binary(package, resource)¶Read and return the contents of the resource within package asbytes.package is either a name or a module object which conforms to thePackage requirements. resource is the name of the resource to openwithin package; it may not contain path separators and it may not havesub-resources (i.e. it cannot be a directory). This function returns thecontents of the resource as bytes.importlib.resources.read_text(package, resource, encodingutf-8, errorsstrict)¶Read and return the contents of resource within package as a str.By default, the contents are read as strict UTF-8.package is either a name or a module object which conforms to thePackage requirements. resource is the name of the resource to openwithin package; it may not contain path separators and it may not havesub-resources (i.e. it cannot be a directory). encoding and errorshave the same meaning as with built-in open(). This functionreturns the contents of the resource as str.importlib.resources.path(package, resource)¶Return the path to the resource as an actual file system path. Thisfunction returns a context manager for use in a with statement.The context manager provides a pathlib.Path object.Exiting the context manager cleans up any temporary file created when theresource needs to be extracted from e.g. a zip file.package is either a name or a module object which conforms to thePackage requirements. resource is the name of the resource to openwithin package; it may not contain path separators and it may not havesub-resources (i.e. it cannot be a directory).importlib.resources.is_resource(package, name)¶Return True if there is a resource named name in the package,otherwise False. Remember that directories are not resources!package is either a name or a module object which conforms to thePackage requirements.importlib.resources.contents(package)¶Return an iterable over the named items within the package. The iterablereturns str resources (e.g. files) and non-resources(e.g. directories). The iterable does not recurse into subdirectories.package is either a name or a module object which conforms to thePackage requirements.
