NAME

       py3versions - print python3 version information

SYNOPSIS

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

DESCRIPTION

       py3versions  prints  information  about installed, supported python3 runtimes, the default
       runtime, 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.
