I am new to python scritping for geoprocessing tasks so I am not looking for a really complex method just a simple and straightforward way to do this.I don't follow what you're trying to do here.

Usage. The tool is typically used with the Add Locations tool to transfer fields from the input features to the sublayers.

Then use the field mappings in the Add Locations tool to provide input ...Solution. Verify whether the feature class or table is locked by another user or is read-only.

The table containing the x- and y-coordinates that define the locations of the point features that will be created. Table View. Output Feature Class. The feature class containing the output point features. Feature Class. X Field. The field in the input table that contains the x-coordinates (or longitude). Field.Summary. The FieldMap object provides a field definition and a list of input fields taken from a set of tables or feature classes.. Discussion. The properties of the FieldMap object include the start and end position of an input text value, so an output value can be created using a slice of an input value. If a FieldMap object contains multiple input fields from the same table or feature class ...This operation adds features to the associated feature layer or table (POST only). The addFeatures operation is performed on a feature service layer resource. The operation returns the results of the edits in an array of edit result objects.

String shapeFieldName=featureClass.ShapeFieldName; // Get the feature class fields collection and find the shape field index. IFields fields=featureClass.Fields;Additional fields will become part of a composite index (that is, an index created on multiple fields in a table). A new index is added for each unique index name in a geodatabase. If an index name already exists, it must be dropped before it can be updated. For enterprise geodatabase data that is not registered as versioned, you can add both ...To calculate area and length in Python, use the getArea and getLength methods with a method and unit type. !shape.getArea( 'GEODESIC', 'SQUAREKILOMETERS' )!

If this was a geodatabase table or feature class, you could use something like arcpy.AddField_management(mytable, 'diff90_10', 'LONG') to add your new field. cursor = arcpy.da.UpdateCursor(population, ["1990", "2000"])6. Field mappings are kind of cumbersome in ArcGIS. First you create a fieldmappings object, then create fieldmap, then add input fields and define output fields. Also, you can add the entire table to the mapping like: myMapping = arcpy.FieldMappings() myMapping.addTable(path_to_the_table) arcpy.Append_management(fc, fc_out, "NO_TEST", myMapping)…
