The following is supposed to write the partial content of four Attribute Tables [AT] to a single CSV file. While it finishes “successfully”, it only writes the last of the four tables to the specified CSV file [MyOutput8.csv]. I had though that the statement arcpy.env.overwriteOutput=True on line 19 would address that but clearly I’m wrong.     The CSV output looks like this, which is correct, except for the missing three AT’s that should precede it.     Advice, please. Thank you so much.   ... View more

This is for ArcGIS Desktop 10.8.1, Python 2.7.   The purpose of this script is to examine Attribute Tables associated with a set of Feature Classes and to extract from those tables a set of fields, writing those fields to a single csv file. The following script threw the error “’None Type’ object is not iterable” that was flagged on Line 20, highlighted in the figure below.   After reading several threads about None Type [here’s one from Geonet] I’ve decided that I’m just not smart enough to sort this out by myself nor have sufficient experience with Python to do so.     Here’s what I’ve done to narrow things down:   Ran a script to print out the FC’s that would be listed by line 12. This gave me the expected answer. Checked to make sure that the field names listed on line 26 were spelled and capitalized correctly. They were and were able to produce a csv file for a single FC.   To get to this point, I’ve been the beneficiary of help from several Geonet denizens for which I am very grateful. I hate to keep asking and not giving, but here I am and would be grateful, yet again, for some suggestion or two about what I should be looking for to resolve this error.     ... View more

This is for ArcGIS 10.8.1 and Python 2.7   Using Blake Terhune’s solution [thank you, Blake] shown in the ESRI Community article Export Attribute Table to .csv as a basis to create a .csv file from the selected contents of an attribute table, I need to go one step further and modify that script so that it will cycle through a defined number of Attribute Tables within a defined .gdb. [Leaving the changes out, the script works fine for a single FC.]   To do that I made these changes, which, it appears, to have been wrong. Here’s the modified script with the modifications highlighted in yellow:   Modified CSV Script   1. I added line 12 which is intended to create a variable that extracts all FC’s that end with “03”. 2. Then modified line 15 so that that variable defined the array of input tables. 3. Finally added a for-loop as line 20 to cycle through those tables defined by line 15, outputting a – hopefully – concatenated .csv file containing all of the Attribute Table entries.   This didn’t work as shown by this run-time result:   ArcPy Error  I checked to see if all the Fields defined in line 25 were spelled correctly – as I gotten a similar error when there was a problem with the field list – but they were all spelled and capitalized correctly. I would be grateful for some guidance on where I have gone wrong, please.   Thanks so much,   ... View more
