Re: Arcpy to check if the AcceptConnections check box is True or False

From what I can tell there must not be a property to describe the state of the check box. That is all I am looking for. I have another route I can go but if there was this option then that would make it easy.  ... View more

Re: Datetime field in da.SearchCursor to csv file

Another way:     fc = r'path/to/featureclass' dateformat = '%Y-%m-%d' datefields = [d.name for d in arcpy.ListFields(fc, field_type='Date')] recs = [] with arcpy.da.SearchCursor(fc, ['OID@', 'TheDate']) as rows: for row in rows: recs += [r if f not in datefields else r.strftime(dateformat) for r, f in zip(row, rows.fields)] print(recs)     Or as a iterator:   def datecursor(fc, dateformat, *args, **kwargs): datefields = [d.name for d in arcpy.ListFields(fc, field_type='Date')] with arcpy.da.SearchCursor(fc, *args, **kwargs) as rows: for row in rows: yield [r if f not in datefields else r.strftime(dateformat) for r, f in zip(row, rows.fields)] fc = r'path/to/featureclass' dateformat = '%Y-%m-%d' recs = [row for row in datecursor(fc, dateformat, ['OID@', 'TheDate'])]   ...

Re: arcpy

Sorry if I convolute this situation more for you @Mick , but I just want to add that you can use a wildcard argument with ListFiles() to only return txt files. import arcpy import os inPut = r'D:\Downloads\aatester' arcpy.env.workspace = inPut myList = arcpy.ListFiles("*.txt") for fileName in myList: out = os.path.join(inPut, f"{fileName[:-4]}.txt") print(out) with open(out, "a") as k: k.write('Hellow') Additionally, I updated your path construction to use os.path.join() so it reliably does the separator. You will also notice the f string formatting for the file name. This will function the same but I just wanted to demonstrate there are multiple ways to accomplish something. ... View more

Re: Access Secured Feature Service using JavaScript API 4.0

Re: Determine if Address is inside of a polygon

An address from a form is just a string. You will need to geocode it to determine the actual spatial location (geometry) in order to perform geometry operations with it, like testing if it's located inside a polygon. ... View more

Re: Create a script tool that uses multiprocessing

@JakeSkinner  yes I used your code as is, with my micro tweaks as described above, so I was writing to your file geodatabase... It worked for me. I too have discovered that multiprocessing is not always faster, I think there is a big hit on instantiating the geoprocessor, tool validation etc; so you only get a performance boost if what you are splitting out inherently has a long run time (e.g. munching some large raster dataset). Weirdly only today I was looking at manifold.net ... ... View more

Re: Using field lists in arcpy.da update cursor to calculate percentage

Thank you! I ended up doing something a little different because even when I changed my fieldnames to be the appropriate format, it was throwing an error. Here's what I came up with:       # Calculate sum field for sum of all values crop_table_all = r'E:\FATHOM\2020FATHOM\Analysis\MR_cropscape_2016_FPstats_02062021.gdb\Cropscape_MR_floodplain_statsALL' cropfieldlist = [f.name for f in arcpy.ListFields(crop_table_all,"VALUE_*","")] print (cropfieldlist) fieldName1 = "VALUE_SUM" arcpy.AddField_management(crop_table_all, fieldName1, "DOUBLE","", "", "", "", "") with arcpy.da.UpdateCursor(crop_table_all, cropfieldlist) as cursor: for row in cursor: row[-1] = sum(row[:-2]) cursor.updateRow(row) fieldName5 = "Pct_Ag_Cropscape_FATHOM" fieldName2 = "Pct_AgPlus_FATHOM" fieldName3 = "Pct_Natural_FATHOM" fieldName4 = "Pct_Developed_FATHOM" fieldName6 = "Pct_Disturbed_FATHOM" arcpy.AddField_management(crop_table_all, fieldName5, "DOUBLE","", "", "", "", "") arcpy.AddField_management(crop_table_all, fieldName2, "DOUBLE","", "", "", "", "") arcpy.AddField_management(crop_table_all, fieldName3, "DOUBLE","", "", "", "", "") arcpy.AddField_management(crop_table_all, fieldName4, "DOUBLE","", "", "", "", "") arcpy.AddField_management(crop_table_all, fieldName6, "DOUBLE","", "", "", "", "") expression2 = "((!Value_1! + !Value_2! + !Value_3! + !Value_5! + !Value_12! + !Value_13! + !Value_42! + !Value_26! + !Value_52! + !Value_225! + !Value_226! + !Value_228! + !Value_232! + !Value_237! + !Value_238! + !Value_239! + !Value_240! +!Value_241! + !Value_254!) / (!VALUE_sum!)) *100" expression3 = "(( !Value_111!+ !Value_131!+ !Value_141!+ !Value_142!+ !Value_143!+ !Value_152!+ !Value_190!+ !Value_195!) / (!VALUE_sum!)) *100" expression4 = "((!VALUE_121!+!VALUE_122!+!VALUE_123!+ !VALUE_124!) / (!VALUE_sum!)) *100" expression5 = "100 - (!Pct_Natural_FATHOM! + !Pct_Disturbed_FATHOM!)" expression6 = "(!Pct_Ag_Cropscape_FATHOM! + !Pct_Developed_FATHOM!)" arcpy.CalculateField_management(crop_table_all, fieldName5, expression5, "PYTHON_9.3") arcpy.CalculateField_management(crop_table_all, fieldName2, expression2, "PYTHON_9.3") arcpy.CalculateField_management(crop_table_all, fieldName3, expression3, "PYTHON_9.3") arcpy.CalculateField_management(crop_table_all, fieldName4, expression4, "PYTHON_9.3") arcpy.CalculateField_management(crop_table_all, fieldName6, expression6, "PYTHON_9.3")     ...
