I found this to be easy to do because the object's .properties attribute created a map with the property name as the key and value as the value.
Once I had this, I could make the difference between the two cards, and I have the answer I was looking for.
Each of the objects has the extension .properties. This works like Python.dict.
Example
object1.properties - object2.properties
, object1 2, , ( + ), object2. 2 , .
