Develop a script with arcpy in arcgis that detects if a type is repeated for the same id , As we find NA2 repeated twice for an id 2 for example.

You create another field named validation and if we have 2 same types repeated we return " error" and the name of the type in error. So, in the validation we find error in NA2.
I will share the data for the awarded person to work directly on it .
The person who will post in this project should have skills in arcpy and GIS.
