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.
