pip-query

#!/usr/bin/env python3

import operator
import subprocess
import sys

import pkg_resources
try:
    from pip._internal.commands.list import tabulate
except ImportError:
    from pip.commands.list import tabulate


def query(file):
    proc = subprocess.Popen(['pacman', '-Qqo', file], stdout=subprocess.PIPE,
                            stderr=subprocess.PIPE, universal_newlines=True)
    out, err = proc.communicate()
    return out.strip()


def main():
    packages = sorted(pkg_resources.WorkingSet(), key=operator.attrgetter('project_name'))
    if not packages:
        return 0
    data = [(pkg.project_name, pkg.version, query(pkg.egg_info or pkg.path), ) for pkg in packages]
    data.insert(0, ('Package', 'Version', 'Owner', ))
    rows, sizes = tabulate(data)
    rows.insert(1, ' '.join(map(lambda x: '-' * x, sizes)))
    for row in rows:
        print(row)
    return 0


if __name__ == '__main__':
    sys.exit(main())

Usage example:

$ sudo pacman -S python-pip wheel  # install some python packages with pacman
$ sudo pip install tqdm  # install some python packages with pip
$ ./pip-query
    Package    Version Owner
    ---------- ------- -----------------
    appdirs    1.4.3   python-appdirs
    packaging  17.1    python-packaging
    pip        9.0.1   python-pip
    pyparsing  2.2.0   python-pyparsing
    setuptools 39.2.0  python-setuptools
    six        1.11.0  python-six
    tqdm       4.23.4
    wheel      0.31.1  python-wheel

tqdm has no Owner, as expected.
