I have a script tool that populates a "season" field based on the date of the point. For example, if the point is between Nov 1 and Feb 29, the "season" field is "Winter". It also looks to see if a particular individual is in a "nesting" or "brooding" list and, if so, that influences the season type. The tool works fine when I copy and paste the code in to the python window in ArcGIS Pro 2.4, but when run as a script tool, I get the following error: AttributeError: type object 'datetime.datetime' has no attribute 'datetime'.  The error is thrown on line 11 below. Everything looks fine in the output and the print statements as I run it in the python window, as far as I can tell. It's probably something simple as this is the first time I've used the datetime module, but I'm confused why as a tool it won't recognize the datetime.datetime attribute import datetime full = "name of feature class" nesting = ['bird1', 'bird2', 'bird3'] brooding = ['bird4', 'bird5', 'bird6'] with arcpy.da.UpdateCursor(full, ['Date', 'Month', 'Year', 'Season', 'SEX', 'NAME']) as cursor: for row in cursor: if row[3] == None: d = datetime.datetime(int(row[2]), int(row[1]), int(row[0])) print(d) arcpy.AddMessage(d) if row[4] == 'MALE': if d >= datetime.datetime(int(row[2]), 3, 1) and d <= datetime.datetime(int(row[2]), 6, 15): row[3] = 'Breed' cursor.updateRow(row) elif d >= datetime.datetime(int(row[2]), 6, 16) and d <= datetime.datetime(int(row[2]), 8, 31): row[3] = 'Summer' cursor.updateRow(row) elif d >= datetime.datetime(int(row[2]), 9, 1) and d <= datetime.datetime(int(row[2]), 10, 31): row[3] = 'Fall' cursor.updateRow(row) elif d >= datetime.datetime(int(row[2]), 11, 1) and d <= datetime.datetime(int(row[2]), 12, 31): row[3] = 'Winter' cursor.updateRow(row) elif d >= datetime.datetime(int(row[2]), 1, 1) and d <= datetime.datetime(int(row[2]), 2, 29): row[3] = 'Winter' cursor.updateRow(row) elif row[4] == 'FEMALE': #fall if d > datetime.datetime(int(row[2]), 8, 31) and d < datetime.datetime(int(row[2]), 11, 1): row[3] = 'Fall' cursor.updateRow(row) #winter elif d > datetime.datetime(int(row[2]), 10, 31) and d <= datetime.datetime(int(row[2]), 12, 31): row[3] = 'Winter' cursor.updateRow(row) elif d >= datetime.datetime(int(row[2]), 1, 1) and d < datetime.datetime(int(row[2]), 3, 1): row[3] = 'Winter' cursor.updateRow(row) #Breed elif row[5] not in nesting and row[5] not in brooding and d >= datetime.datetime(int(row[2]), 3, 1) and d <= datetime.datetime(int(row[2]), 6, 15): row[3] = 'Breed' cursor.updateRow(row) elif row[5] in nesting and d >= datetime.datetime(int(row[2]), 4, 10) and d <= datetime.datetime(int(row[2]), 6, 20): row[3] = 'Nest' cursor.updateRow(row) elif row[5] in brooding and d >= datetime.datetime(int(row[2]), 5, 5) and d <= datetime.datetime(int(row[2]), 9, 1): row[3] = 'Brood' cursor.updateRow(row) elif row[5] not in brooding and d >= datetime.datetime(int(row[2]), 6, 16) and d <= datetime.datetime(int(row[2]), 8, 31): row[3] = 'Summer' cursor.updateRow(row) else: print('assign point manually') else: print('Type already calculated') cursor.updateRow(row) print('done') arcpy.AddMessage("Complete")‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

I have a point feature class that has a unique ID field and a julian date field. I also have a pile of rasters in a geodatabase that have daily values that I want to extract to the corresponding date in the point file. I have already written a script that goes through and renamed them so that the julian date is tagged on to the end of the name of the raster. To do this, I have the following code: input = point feature class #Iterate through to extract values to points based on date arcpy.env.workspace = #geodatabase with the rasters fl = arcpy.ListRasters() dict = {} for feature in fl: j = feature[-5:-1] + feature[-1]#returns the julian date with arcpy.da.SearchCursor(input, ["julian"]) as cursor: for row in cursor: if row[0] == int(j): temp = #temporary output string table = arcpy.sa.ExtractValuesToPoints(input, r'string for geodatabase' + feature, r"ouput geodatabase" + feature + "_testtable") with arcpy.da.SearchCursor(table, ['ID', 'RASTERVALU']) as cursor2: for row2 in cursor2: ID = row2[0] value = row2[1] dict.update({ID : value}) arcpy.Delete_management(table) else: print('not equal' + str(row[0])) with arcpy.da.UpdateCursor(input, ['ID', "Value column"]) as cursor: for row in cursor: row[1] = dict[row[0]] cursor.updateRow(row)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I think the problem is line 15; the input for the Extract Values to Points tool is being overwritten by the last raster that it iterates over. So, the values for November 6th are writing over all of the previous dates in the dictionary and subsequently the point feature class.  How do I code this so that it only runs the Extract Values to Points tool on the selected row in the search cursor? ...

I have a field for aspect (short integer) with values ranging from 1-4. I want to have 3 additional columns: aspect2, aspect3, aspect4 that are calculated based on the aspect field (for example, if the aspect field is 2, then aspect2 = 1, aspect3 =0 and aspect4 =0). Here is the code I have: arcpy.AddField_management(input, 'aspect2', 'SHORT') arcpy.AddField_management(input, 'aspect3', 'SHORT') arcpy.AddField_management(input, 'aspect4', 'SHORT') with arcpy.da.UpdateCursor(input, ['aspect', 'aspect2', 'aspect3', 'aspect4']) as cursor: for row in cursor: if cursor[0] == 2: cursor[1] = 1 cursor[2] = 0 cursor[3] = 0 cursor.updateRow(row) elif cursor[0] == 3: cursor[1] = 0 cursor[2] = 1 cursor[3] = 0 cursor.updateRow(row) elif cursor[0] == 4: cursor[1] = 0 cursor[2] = 0 cursor[3] = 1 cursor.updateRow(row) else: cursor[1] = 0 cursor[2] = 0 cursor[3] = 0 cursor.updateRow(row)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ When I run it, I get the following error: Traceback (most recent call last): File "<string>", line 19, in <module> TypeError: 'da.UpdateCursor' object does not support item assignment I'm not sure if it's a basic syntax issue (it's very possible) or I'm not thinking about it correctly. Any ideas are greatly appreciated. ... View more
