Using GetParameterAsText() with Cursor.

anTonialcaraz

Hi, I'm trying to use the GetParameterAsText() for user input.

When I use a value instead, it works fine but not with GetParameterAsText()

Any help will be greatly appreciate.

               NOT WORKING                                                                 WORKING

AreaFilter = arcpy.GetParameterAsText(0)

cur = arcpy.UpdateCursor(outFeatureAREA)

for row in cur:

    if row.F_AREA <= AreaFilter:
        cur.deleteRow(row)
        cur.updateRow(row)

del row
del cur

Hi, I was being too optimistic.

Here is the whole code:

===============================================================================

import arcpy

import string

import math

from arcpy import env

arcpy.env.overwriteOutput=True

from arcpy.sa import *

arcpy.CheckOutExtension("Spatial")

# Set workspace location, extent and variables

INWorkspace = r"D:\PROGRAMMES\LFP_Source_Rocks\ArcGIS\00_LFP_GLOBAL\00_LFP_GLOBAL_Python\WORK_TEST_space\ISLAND_Effect\INPUT.gdb"

arcpy.env.extent = arcpy.Extent(-180.0, -90.0, 180.0, 90.0)

inFeature = INWorkspace + "\\" + "G_SL_HiStand_20M_J_Tith_m2_0"

outFeature = INWorkspace + "\\" + "HiStand_polygon"

outFeatureAREA = INWorkspace + "\\" + "HiStand_polygonAREA"

# Convert polyline feature to polygon

arcpy.FeatureToPolygon_management(inFeature, outFeature, "","NO_ATTRIBUTES", "")

# Calculate area in KM2

arcpy.CalculateAreas_stats(outFeature, outFeatureAREA)

Expr = "(!F_AREA!) / 1000000"

arcpy.CalculateField_management(outFeatureAREA,"F_AREA",Expr,"PYTHON")

# Filter by Area

AreaFilter = float(arcpy.GetParameterAsText(0))

cur = arcpy.UpdateCursor(outFeatureAREA)

for row in cur:

    if row.F_AREA <= AreaFilter:

        cur.deleteRow(row)

        cur.updateRow(row)

del row

del cur

===============================================================================

If I run the script up to "# Filter by Area" it will create a Polygon Feature Class (HiStand_polygonAREA) with a field called "F_Area" holding all area values.

If I then run the script only from "# Filter by Area" with "HiStand_polygonAREA" as the input feature class (outFeatureAREA) it works.

If I run the whole script at once it still produces the output required (HiStand_polygonAREA) but it doesn't perform anything within the cursor part, for example, deleting those rows <= than 1000; and I get this:

So, I'm lost now.
