You can do:

$ df -Ph | awk '/^\// {print $1"\t"$2"\t"$4}' | python -c 'import json, fileinput; print json.dumps({"diskarray":[dict(zip(("mount", "spacetotal", "spaceavail"), l.split())) for l in fileinput.input()]}, indent=2)'
{
  "diskarray": [
    {
      "mount": "/dev/disk1", 
      "spacetotal": "931Gi", 
      "spaceavail": "623Gi"
    }, 
    {
      "mount": "/dev/disk2s2", 
      "spacetotal": "1.8Ti", 
      "spaceavail": "360Gi"
    }
  ]
}
