Getting python3-using packages:
$ for f in $(repoquery --whatrequires python3) ; do echo $f ; repoquery --source $f ; done > sources.txt $ grep src.rpm sources.txt | sort | uniq | wc -l 130
but it's showing some duplicates; adding filtering shows 105 src.rpms:
$ grep src.rpm sources.txt | python -c "import sys, re; print('\n'.join([re.match('(.*)-(.*)-(.*).src.rpm', line).group(1) for line in sys.stdin.readlines()]))"| sort |uniq ATpy babel bpython cobbler deltarpm dreampie lcgdm libselinux libsemanage loook metagoofil mpi4py mysql-connector-python nfoview nordugrid-arc numpy pycmd pyfits pygobject3 pyke pyp2rpm pyparsing PyQt4 pyshp pytest python3 python3-cairo python3-chardet python3-cherrypy python3-dateutil python3-postgresql python3-zope-fixers python-amqplib python-ansi2html python-anyjson python-asciitable python-auth-credential python-beaker python-BeautifulSoup python-beautifulsoup4 python-cmd2 python-coverage python-crypto python-cvxopt python-decorator python-dirq python-docutils python-easygui python-enchant python-execnet python-feedparser python-flexmock python-html5lib python-httplib2 python-inotify python-jinja2 python-lxml python-mako python-manuel python-markdown python-markdown2 python-markupsafe python-messaging python-mglob python-minimock python-mock python-networkx python-nose python-nose1.1 python-pbs python-pip python-pkgwat-api python-ply python-psutil python-psycopg2 python-py python-pygments python-pyro python-requests python-restauth python-restauth-common python-setproctitle python-setuptools python-simplegeneric python-six python-sleekxmpp python-smbc python-smbpasswd python-sphinx python-sqlalchemy python-straight-plugin python-tempita python-tornado python-urwid python-zmq python-zope-event PyYAML revisor ris-linux scipy sip stomppy uwsgi waf znc
