PY3VERSIONS()                                                                          PY3VERSIONS()

NAME
       py3versions - print python3 version information

SYNOPSIS
       py3versions [-h] [-v] [<options>]

DESCRIPTION
       py3versions  prints information about installed, supported python3 runtimes, the default run‐
       time, and parses the information of the PythonVersion fields in the package control file  for
       Python3.

OPTIONS
       -d, --default
              Show the default python3 version.

       -s, --supported
              Show  the  supported python3 versions.  List is lowest version to highest version with
              the default version last (e.g. python3.4 python3.6 python3.5 if  python3.4,  3.5,  and
              3.6 are supported, but python3.5 is the default python3).

       -r, --requested [<version string>|<control file>]
              Reads the value of the X-Python3-Version field in the source section of a control file
              and  shows  all  matching  python3 versions. The parameter is interpreted as a version
              string, if it is not the name of a file. If the X-Python3-Version field is missing, it
              will fall back to list the supported Python3 versions after  checking  debian/control.
              Versions  less  than  3  are ignored. The keyword all is ignored because it covers all
              Python2 versions.  The former keyword current is not  supported  at  all  in  Python3.
              Uses the same sort order as the -s, --supported option.

       -i, --installed
              Show the installed supported python3 versions.

       --min-supported
              Show the minimum supported python3 version.

       --max-supported
              Show the maximum supported python3 version.

       -v, --version
              Limit the output to the version numbers of the python3 versions.

       -h, --help
              Print a help text.
