Add Field. Adds a new field to a table or the table of a feature class or feature layer, as well as to rasters with attribute tables. Add Fields (multiple) Adds new fields to a table, feature class, or raster. Add Global IDs. Adds global IDs to a list of geodatabase feature classes, tables, and feature datasets. Add GPS Metadata Fields6. 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)To force the POINT_X and POINT_Y values to be in a coordinate system different than the input dataset, set the Output Coordinate System environment. If points are moved after using Add XY Coordinates, their POINT_X and POINT_Y values, and POINT_Z and POINT_M values—if present—must be recomputed by running Add XY Coordinates again. ….

I am working on a Python script using Arcpy. It creates a shape file, and then adds fields to it with names coming from user input. From the string the user has entered I need to produce a valid field name. I thought arcpy.ValidateFieldName() would accomplish this. However, I am having problems. Consider the code below:The function returns a field mapping object that can be used in an Append, etc: def fmapForDict(inputDataset, mappingDict): fieldMappings = arcpy.FieldMappings() for sourceField in mappingDict: fMap = arcpy.FieldMap() fMap.addInputField(inputDataset, sourceField) outField = fMap.outputField. outField.name = mappingDict[sourceField]Usage. Use this tool to add new features or other data from multiple datasets to an existing dataset. This tool can append point, line, or polygon feature classes, tables, rasters, annotation feature classes, or dimension feature classes to an existing dataset of the same type. For example, several tables can be appended to an existing table ...
