The values in the list_of_fields are already strings, the UpdateCursor accepts either a list of fields or a string with the name of the field. There is no need to do any kind of formatting to the values. just do: for i in list_of_fields: with arcpy.da.UpdateCursor(dataset, i) as cursor: for row in cursor: row[0]=row[0].strip() cursor.updateRow(row)Create lists of data. One of the foremost tasks in a batch processing script is cataloging the available data so it can iterate through the data during processing. ArcPy has a number of functions built specifically for creating such lists. The result of each of these functions is a list, which is a list of values.Field オブジェクトの type プロパティ値は、 [フィールドの追加 (Add Field)] ツールの field_type パラメーターが使用するキーワードとは完全には一致しませんが、すべての Field オブジェクトの type 値をこのパラメーターへの入力として使用できます。. フィールド ...

I can do this easily in desktop ArcGIS, but have several hundred rasters to process, so am trying to use an arcpy for loop. It seems, if I specify the calculation expression outside of the For loop, I can get it to run a calculation on each row in the field, but can't get the derived value, using all the values in the field, into the calculation.Here is an example on how to do this. The below code will append all the rows from the population field to a list using a search cursor, then it will sum the list. import arcpy. from arcpy import env. env.workspace = r"C:\temp\python\test.gdb". fc = "Cities". list = [] rows = arcpy.SearchCursor(fc) for row in rows:summed_total = 0 with arcpy.da.SearchCursor(fc, "field to be totaled") as cursor: for row in cursor: summed_total = summed_total + row[0] Something like this would work. Replace what's in quotes with your field name, or with a list of fields you're going to be working with. Replace fc with the feature that holds the field.
