create specified point with python

Question

with python, i want to create point feature class. how to create point in specified coordinate but not from a file which contain coordinate. i have try to make the script but there was an error " 'list' object is not callable. ". anyone have an explanation?

# Process: Add Field...
gp.AddField_management(InputFC__2_, "V", "DOUBLE", "", "", "", "", "NON_NULLABLE", "NON_REQUIRED", "")

# Process: Calculate Field...
gp.CalculateField_management(InputFC, "V", " * ", "VB", "")

# Process: Summary Statistics...
gp.Statistics_analysis(InputFC__3_, InputFC_Statistics_dbf, "D SUM;V SUM", "")
 
# create the output feature class using the spatial reference object
gp.CreateFeatureClass(New_Folder,OutputFC,"Point","ENABLED","DISABLED",spatialRef)

gp.AddField_management(OutputFC,"D","DOUBLE","", "", "", "", "NON_NULLABLE", "NON_REQUIRED", "")
gp.AddField_management(OutputFC__2_,"H","DOUBLE","", "", "", "", "NON_NULLABLE", "NON_REQUIRED", "")
 
rows = gp.SearchCursor(InputFC_Statistics_dbf)
row = rows.Next()
while row:
 count1 = row.SUM_V
 count2 = row.SUM_D
 
 prows = gp.InsertCursor(OutputFC__3_)
 # create point object to create feature
 pnt = gp.CreateObject("Point")
 pnt.id = 1
 pnt.x = 566020
 pnt.y = 252044
 
 prow = prows.NewRow()
 prow.Shape = Point
 prow.Dt = count2
 prow.H = count1 / count2
 Point.Add(pnt)
 prows.InsertRow(prow)
 row = rows.Next()

del prow, prows
del row, rows

I think you're missing a value for the (optional) template parameter in CreateFeaturecClass

CreateFeatureClass_management (out_path, out_name, geometry_type, template, has_m, has_z, spatial_reference, config_keyword, spatial_grid_1, spatial_grid_2, spatial_grid_3)

Thanks to Guenter Doerffel, but there is another error with the script, "create feature class" process still didn't work. the error message is:

<class 'arcgisscripting.ExecuteError'>: ERROR 000622: Failed to execute (Create Feature Class). Parameters are not valid.
ERROR 000623: Invalid value type for parameter has_z.

all data type in calculation process is "DOUBLE", and input feature class doesn't has Z values. is the problem in the input file or in script?

Hi,

I wont check through all your code, but there actually is one very prominent error:

you coded:prows = gp.InsertCursor(OutputFC__3_)
# create point object to create feature
pnt = gp.CreateObject("Point")
pnt.id = 1
pnt.x = 566020
pnt.y = 252044

prow = prows.NewRow()
prow.Shape = Point
prow.Dt = count2
prow.H = count1 / count2
Point.Add(pnt)
prows.InsertRow(prow)
row = rows.Next()

which wont work, since you assign Point to the shape of the newly added record ... this does not exist!

try:prows = gp.InsertCursor(OutputFC__3_)
# create point object to create feature
pnt = gp.CreateObject("Point")
pnt.id = 1
pnt.x = 566020
pnt.y = 252044

prow = prows.NewRow()
prow.Shape = pnt

here - to continue I'd use:
prow.SetValue("Dt", count2)
prow.SetValue("H" , count1 / count2)

this line here is wrong anyway and obsolete nowPoint.Add(pnt)

this should be the correct end of your code:
prows.InsertRow(prow)
row = rows.Next()

so altogether this section should read:
prows = gp.InsertCursor(OutputFC__3_)
pnt = gp.CreateObject("Point")
pnt.id = 1
pnt.x = 566020
pnt.y = 252044

prow = prows.NewRow()
prow.Shape = pnt
prow.SetValue("Dt", count2)
prow.SetValue("H" , count1 / count2)
prows.InsertRow(prow)
row = rows.Next()

Hope this helps
Regards
Guenter
