How to access python package metadata from within the python console?

Question

If I have built a python package employing distutils.core, e.g. via

setup(
    ext_package="foo",
    author="me",
    version="1.0",
    description="foo package",
    packages=["foo",],
)

where does all the metadata go (what is it intended for?) and how can I access it from within python. Specifically, how can I access the author information from the python console after doing something like

>>> import foo

Answer 1

One way to access the metadata is to use pip:

import pip

package = [pckg for pckg in pip.get_installed_distributions() 
            if pckg.project_name == 'package_name'][0]
#  package var will contain some metadata: version, project_name and others.

or pkg_resources

from pkg_resources import get_distribution

pkg = get_distribution('package_name')  # also contains a metadata
