InsertCursor

摘要

Inserts rows into a feature class, shapefile, or table. The InsertCursor returns an enumeration object that hands out row objects.

讨论

New row objects can be obtained using the newRow method on the enumeration object into which rows are to be inserted. Each call to insertRow on the cursor creates a new row in the table whose initial values are set to the values in the input row.
