Importlib.metadata is a library that provides for access to installed package metadata. Built in part on Python's import system, this library intends to replace similar functionality in the entry point API and metadata API of pkgresources. Along with importlib.resources in Python 3.7 and newer (backported as importlibresources for older.

Changed in version 3.10: importlib.metadata is no longer provisional.

importlib.metadata is a library that provides for access to installedpackage metadata. Built in part on Python's import system, this libraryintends to replace similar functionality in the entry pointAPI and metadata API of pkg_resources. Along withimportlib.resources in Python 3.7and newer (backported as importlib_resources for older versions ofPython), this can eliminate the need to use the older and less efficientpkg_resources package.

By 'installed package' we generally mean a third-party package installed intoPython's site-packages directory via tools such as pip. Specifically,it means a package with either a discoverable dist-info or egg-infodirectory, and metadata defined by PEP 566 or its older specifications.By default, package metadata can live on the file system or in zip archives onsys.path. Through an extension mechanism, the metadata can live almostanywhere.

Overview¶

Let's say you wanted to get the version string for a package you've installedusing pip. We start by creating a virtual environment and installingsomething into it:

You can get the version string for wheel by running the following:

You can also get the set of entry points keyed by group, such asconsole_scripts, distutils.commands and others. Each group contains asequence of EntryPoint objects.

You can get the metadata for a distribution:

You can also get a distribution's version number, list itsconstituent files, and get a list of the distribution'sDistribution requirements.

Functional API¶

This package provides the following functionality via its public API.

Entry points¶

The entry_points() function returns a collection of entry points.Entry points are represented by EntryPoint instances;each EntryPoint has a .name, .group, and .value attributes anda .load() method to resolve the value. There are also .module,.attr, and .extras attributes for getting the components of the.value attribute.

Query all entry points:

The entry_points() function returns an EntryPoints object,a sequence of all EntryPoint objects with names and groupsattributes for convenience:

EntryPoints has a select method to select entry pointsmatching specific properties. Select entry points in theconsole_scripts group:

Equivalently, since entry_points passes keyword argumentsthrough to select:

Pick out a specific script named 'wheel' (found in the wheel project):

Equivalently, query for that entry point during selection:

Inspect the resolved entry point:

The group and name are arbitrary values defined by the package authorand usually a client will wish to resolve all entry points for a particulargroup. Read the setuptools docsfor more information on entry points, their definition, and usage.

Compatibility Note

The 'selectable' entry points were introduced in importlib_metadata3.6 and Python 3.10. Prior to those changes, entry_points acceptedno parameters and always returned a dictionary of entry points, keyedby group. For compatibility, if no parameters are passed to entry_points,a SelectableGroups object is returned, implementing that dictinterface. In the future, calling entry_points with no parameterswill return an EntryPoints object. Users should rely on the selectioninterface to retrieve entry points by group.

Distribution metadata¶

Every distribution includes some metadata, which you can extract using themetadata() function:

The keys of the returned data structure, a PackageMetadata,name the metadata keywords, andthe values are returned unparsed from the distribution metadata:

PackageMetadata also presents a json attribute that returnsall the metadata in a JSON-compatible form per PEP 566:

Changed in version 3.10: The Description is now included in the metadata when presentedthrough the payload. Line continuation characters have been removed.

New in version 3.10: The json attribute was added.

Distribution versions¶

The version() function is the quickest way to get a distribution's versionnumber, as a string:

Distribution files¶

You can also get the full set of files contained within a distribution. Thefiles() function takes a distribution package name and returns all of thefiles installed by this distribution. Each file object returned is aPackagePath, a pathlib.PurePath derived object with additional dist,size, and hash properties as indicated by the metadata. For example:

Once you have the file, you can also read its contents:

You can also use the locate method to get a the absolute path to thefile:

In the case where the metadata file listing files(RECORD or SOURCES.txt) is missing, files() willreturn None. The caller may wish to wrap calls tofiles() in always_iterableor otherwise guard against this condition if the targetdistribution is not known to have the metadata present.

Distribution requirements¶

To get the full set of requirements for a distribution, use the requires()function:

Package distributions¶

A convenience method to resolve the distribution ordistributions (in the case of a namespace package) for top-levelPython packages or modules:

New in version 3.10.

Distributions¶

While the above API is the most common and convenient usage, you can get allof that information from the Distribution class. A Distribution is anabstract object that represents the metadata for a Python package. You canget the Distribution instance:

Thus, an alternative way to get the version number is through theDistribution instance:

There are all kinds of additional metadata available on the Distributioninstance:

The full set of available metadata is not described here. See PEP 566for additional details.

Extending the search algorithm¶

Because package metadata is not available through sys.path searches, orpackage loaders directly, the metadata for a package is found through importsystem finders. To find a distribution package's metadata,importlib.metadata queries the list of meta path finders onsys.meta_path.

The default PathFinder for Python includes a hook that calls intoimportlib.metadata.MetadataPathFinder for finding distributionsloaded from typical file-system-based paths.

The abstract class importlib.abc.MetaPathFinder defines theinterface expected of finders by Python's import system.importlib.metadata extends this protocol by looking for an optionalfind_distributions callable on the finders fromsys.meta_path and presents this extended interface as theDistributionFinder abstract base class, which defines this abstractmethod:

The DistributionFinder.Context object provides .path and .nameproperties indicating the path to search and name to match and maysupply other relevant context.

What this means in practice is that to support finding distribution packagemetadata in locations other than the file system, subclassDistribution and implement the abstract methods. Then froma custom finder, return instances of this derived Distribution in thefind_distributions() method.
