Get IronPython Version from path ipy in Powershell

gistfile1.ps1

function Get-IpyVersionFromPath 
{
  .{
    $version = ''
    $ipyPath = Get-Command ipy | Select-Object -ExpandProperty Definition 
    if( [string]::IsNullOrEmpty($ipyPath) ) { return "IPY not in path" }
    $ipyFolder = split-path $ipyPath
    $ipyDll = join-path $ipyFolder 'IronPython.dll'

    [reflection.assembly]::LoadFrom($ipyDll)
    $py = [ironpython.hosting.python]::CreateEngine()
    $pyv = $py.CreateScope()
    $pyc = $py.CreateScriptSourceFromString("import sys; d = sys.version")
    $pyc.Execute($pyv)
    $d = ($pyv.GetVariable("d") -split ' ')
    $version = $d[0]
  } | Out-Null
  $version
}
Write-host (Get-IpyVersionFromPath)

Could also use the following if you don't need to interact with IronPython:
(ipy -c "import sys; print sys.version") | Out-String
