py3versions - print python3 version information
py3versions [-h] [-v] [<options>]
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.
- -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.
