Here is a command that i use to compare different python configurations. It includes getting the value of the outputs:

$ python3.6 -c "import sysconfig;print('{}'.format('\n'.join(['{} = {}'.format(v, sysconfig.get_config_var(v)) for v in sorted(sysconfig.get_config_vars(), key=lambda s: s.lower())])))" > /tmp/python36.conf

$ python2.7 -c "import sysconfig;print('{}'.format('\n'.join(['{} = {}'.format(v, sysconfig.get_config_var(v)) for v in sorted(sysconfig.get_config_vars(), key=lambda s: s.lower())])))" > /tmp/python27.conf

$ sdiff /tmp/python36.conf /tmp/python27.conf
