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.

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

       _-h,_ _--help_
              Print a help text.
