From the Export drop-down list, select and click Selected Features. The function takes two arguments, these are a file-path to the input feature class or table and a file-path for the output CSV file (see example down further). How do I continue to go to the next select by attribute using a while statement. Build the first Search Cursor to iterate through the polygon shapefile that contains the values in the field. While there are certainly other ways to do this either in ArcGIS (Desktop or Pro) or through SQL we’ll focus specifically on the needs of Python programmers working with Arcpy who need to generate a list of unique values for an attribute field.

Please provide as much detail as possible. "FIPS_PARIS ='" + fip + "'"), - output with name of attribute at end. This article is specific to using the ArcPy module installed with ArcGIS 10.x.To complete this procedure using Python requires the use of the Search Cursor method to iterate through the values of the field. I have read all the help documents on it and can't make heads or tails on some of it. Thanks that got rid of that part. How can we improve?

The Select by Attribute needs a specific value from the field for each iteration, so an expression variable (exp) is created for this. "Master_TAHI"), - A list of attributes the tool needs to loop through (eg. (eg. finalPdf = arcpy.mapping.PDFDocumentCreate(outPath + “ParcelReport.pdf”) #Specify the map document and the data frame mxd = arcpy.mapping.MapDocument(r”C:MyProjectMyParcelMap.mxd”) df = arcpy.mapping.ListDataFrames(mxd, “Layers”)[0] #Select a parcel using the LocAddress attribute and zoom to selected In Module 2 we’ll cover the Arcpy Data Access module which allows you to insert, update, and delete data from feature classes and tables. So GetParameterAsText(0) will be the 1st row of that section, GetParameterAsText(1) the 2nd and so on. The arcpy.mapping module is a Python scripting library that allows you to open and manipulate map documents and layers.
