I have shapefile with several different fields in which there is data that needs to be converted into random points. Currently I have been using the Create Random Points (Data Management) tool, which works really well but is very timeconsuming when i have a lot of these that I want to process. What I am wondering is if there is a way to automate this with a loop so I only have to do this once per shapefile, or perhaps once per GDB? My coding skills are lacking at best (although I am learning), so I am not sure this will work.
My Idea is that the script should loop through all fields and use the field name as outName and Numfield.
This is what it currently looks like, but I am getting errors which i'm not sure I understand. The latter seems to be because the table field is a join field, but I don't see another way of describing the field other than with the field name.
import arcpy
arcpy.env.overwriteOutput = True
fieldList = ["T_Flekke_spes_mat$_.Heterogen", "T_Flekke_spes_mat$_.Grå", "T_Flekke_spes_mat$_.Bryozo", "T_Flekke_spes_mat$_.Hvit_grov", "T_Flekke_spes_mat$_.Lys_fin", "T_Flekke_spes_mat$_.Mørk_fin", "T_Flekke_spes_mat$_.Uspesifisert"]
for field in fieldList:
outGDB = "D:\ArcGIS\HV\HV.gdb"
outName = field
conFC = "D:\ArcGIS\HV\HV.gdb\Årbogen_lag_1"
numField = field
arcpy.CreateRandomPoints_management(outGDB, outName, conFC, "", numField)
