importlib

Implements import and provides hooks for customising it. Split into sub-packages: importlib.abc, importlib.machinery, importlib.util, importlib.resources, importlib.metadata.

Source-of-record: Lib/importlib/, importlib docs.

Top-level

Function	Effect
import_module(name, package=None)	Import by string.
reload(module)	Re-import.
invalidate_caches()	Clear finder caches.
__import__(...)	Low-level entry, used by import.

importlib.util

spec_from_file_location, module_from_spec, find_spec(name, package=None), resolve_name(name, package), source_from_cache, cache_from_source, spec_from_loader, LazyLoader.

importlib.machinery

ModuleSpec, BuiltinImporter, FrozenImporter, PathFinder, FileFinder, SourceFileLoader, SourcelessFileLoader, ExtensionFileLoader, NamespaceLoader, SOURCE_SUFFIXES, BYTECODE_SUFFIXES, EXTENSION_SUFFIXES, OPTIMIZED_BYTECODE_SUFFIXES, DEBUG_BYTECODE_SUFFIXES, AppleFrameworkLoader (3.13+).

importlib.abc

Abstract bases for the import protocol: Finder (deprecated), MetaPathFinder, PathEntryFinder, Loader, ResourceLoader, InspectLoader, ExecutionLoader, FileLoader, SourceLoader, Traversable, TraversableResources.

importlib.resources

files(package) returns a Traversable. Use .joinpath, .iterdir, .is_file, .is_dir, .read_bytes, .read_text, and the as_file context manager.

importlib.metadata

distribution(name), distributions(), metadata(name), version(name), entry_points(*, group=None, name=None), files(name), requires(name), packages_distributions().
