Arcpy addfield
The Field object's type property values are not an exact match for the keywords used by the Add Field tool's field_type parameter. Despite this, all of the Field object's type values are acceptable values as input to this parameter. The different field types are mapped as follows: Integer to LONG; String to TEXT; SmallInteger to SHORTSummary. Returns a list of fields in a feature class, shapefile, or table in a specified dataset. The returned list can be limited with search criteria for name and field type and will contain Field objects.

It has to work with ArcGIS 10.0 so I have to use arcpy.InsertCursor. But I have a problem, because in the new feature class there is the same number of rows as in input but every row has the same geometry, from last row of previous feature. In 10.2, even using arcpy.InsertCursor, everything is working fine.First, generate a list of field names: existingFields.append(field.name) # add the attribute name to list for each field. Next, compare the list of existing fields with the list of fields the user wants to add: carry on with adding fields. arcpy.AddMessage('Field(s) already exist: ' + duplicateFields)Syntax. The input table or feature class that contains the field to alter. The name of the field to alter. If the field is a required field (isRequired=true), only the field alias can be altered. The new name for the field. The new field alias for the field. Specifies the new field type for the field.
Dan_Patterson ,. I feel quite foolish now because after digging into this a little deeper, I realized I was using the alias instead of the field name.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]Parameters. The feature class or feature layer that will be converted. The location where the output feature class will be created. This can be either a geodatabase or a folder. If the output location is a folder, the output will be a shapefile. The name of the output feature class.The documentation for Add Field contains a couple of examples of a script to add field to an Attribute table. If you are new to python, fill in the GUI dialog for Add Field, then use the Run button's option to write the code for youIndices Commodities Currencies Stocks
Please try not to drastically change the contents your question in response to answers. Rather make an edit and add your refined code as an update with details of what happens. Otherwise it makes the provided answer appear like it's solving a different problem - see @KHibma's answer refers to list.remove() however you have removed all reference to that in your question, so now the first part ...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.It makes it easier to debug and read, and you dont need alot of empty strings: arcpy.AddField_management(in_table=located, field_name="source", ... ….

Here is my code (keep in mind that it is pretty specific to my data and contains lines to test certain stages of the script): import arcpy,sys,os. #Get the Files involved, set some variables. SectorTable = sys.argv[1] SectorShape = sys.argv[2] MaxDev = sys.argv[3] PopulationFC = sys.argv[4]Here is another way you can calculate a string to a text field: arcpy.CalculateField_management (fc, "DFDD", "\"aaa\"", "PYTHON") One way to verify formatting is to setup the tool/parameters in ModelBuilder and then export the model to a python script.
With the ArcGIS API for Python you can automate the process of importing and then publishing data as a web layer. The import process is a fast and easy way to turn static data into live web services that can be displayed, filtered, and edited within your applications. In this tutorial, you will import different file types as items stored in ArcGIS.You're right, I don't generally use that property and took it to mean 'population required' - but I guess that's what non-nullable means. I've had success with the export-XML-import workflow; it changes the database to a textural format which can be manipulated allowing for changes that can't usually be made in a database (like, field name) and if you break it it's only a copy, just create a ...
black couple kissing gif My problem is that the Quad is a numeric field that represents the direct or text label. for example. Quad = 3 (where 1= NW, 2 = NE, 3 = SW, 4 = SE) Township = 16. Range = 42. Section = 36. the output label field needs to be a text field that reads like this: T16S R42W Sec36. Where the S in township and W in range come from the quad = 3 for SW. grams mt morristhe animals' hospital of levittown myList = [] rows = arcpy.SearchCursor(YOURLAYER) for row in rows: if row.YOURFIELD not in myList: myList.append(row.YOURFIELD) del rows del row Share.

For example: unit prints promo code Create a new parameter of Field Mappings and look how one can add fields. User provides all the information necessary to create one or more fields. In your source code, you extract the information you need about each field user supplied. import arcpy. fields_to_add = arcpy.GetParameter(0) #of `Field Mappings` type. nicole sittre nowverizon outage map baltimore9x12 envelope how many stamps Dear Xander, I wonder if it is possible to take width and length of the rectangle from a dbf table..

Once in ModelBuilder you can export the code out as python. To run the code you can either right click it in Windows Explorer and run it with python.exe or copy the code line for line into IDLE (Python GUI), which is installed with ArcGIS.
