I have a field named "arrondissement" (district), which contains as attributes integers from 1 to 20. My task is to create a column for each arrondissement with the ranks (short integers) relative to the shape area for the connecting areas to voting stations of the same district.
I hope it makes sense, not really sure how to do it to be honest I'm lost at the moment. Besides adding a field, perhaps multiple ones with a loop by using ListFields and AddField, I don't really know what else to do.
EDIT:
While figuring out what I have to do, practically creating a field for each arrondise, and in each, rank each FID (which are part of the respective arrondise) by the size of its shape area.
import arcpy
arcpy.env.workspace = "D:/M1 Geomatique/Programmation II/Dossier"
fc = "zones_rattachement.shp"
try:
fieldRoot = "RANG_R"
for counter in range(1,21):
arcpy.AddField_management(fc, fieldRoot + str(counter),'SHORT')
size_rank = 1
numlist = list(range(1,21))
for num in numlist:
arcpy.SelectLayerByAttribute_management(fc, "NEW_SELECTION", "arrondisse = '%c'")
rows = arcpy.UpdateCursor(fc, sort_fields="shape_area D")
for row in rows:
row.setValue("RANG_R1", size_rank)
size_rank += 1
rows.updateRow(row)
