Use Python to add an ordinal to a feature

In the ArcGIS property sheet, the default FID or OID is not contiguous because of the editing changes, and it is often necessary to add sequential serial numbers to the features, which can be done using Python code.

Rec=-1def AutoIncrement (): Global rec Pstart = 1 #起始值为1, modifiable pinterval = 1 #间隔值为1, can be modified if (rec ==-1):   rec = Pstart  E LSE:   REC = rec + pinterval  return rec

Call Method:

AutoIncrement ()
