Python Version Fact

Outputs the python version in pythonversion and the python major.minor version in pythonmmversion.

require 'facter'

pythonversion = nil
if FileTest.exists?("/usr/bin/python")
	pythonversion = %x{python -V 2>&1}.split(" ")[1]
end

Facter.add("pythonversion") do
	setcode do
		pythonversion
	end
end

Facter.add("pythonmmversion") do
	pythonmmversion = nil
	if pythonversion != nil
		pythonversionsplit = pythonversion.split(".")
		pythonmmversion = pythonversionsplit[0] + "." + pythonversionsplit[1]
	end
	setcode do
		pythonmmversion
	end
end

ToDo

Maybe make it a little more path agnostic regarding the location of the python executable.
