comment Arcmap record value is not displaying entirely
Sorry, I thought you were saying that the field values were written there via Python but I think you are saying that they are of unknown origin and first showed up when you tried to process them using Python. It may be worth editing your question to try and make that clearer.

What have you tried? Where are you stuck? Please edit your question to provide more details as advised when you initially posted this as an answer to another question.

comment Arcmap record value is not displaying entirely
Why don't you just type 101 or 101RADIAT into that field and see if it overwrites the unwanted value? I've not tested but your co-worker's theory about a \n sounds reasonable to me. Without your question including a Python code snippet that shows how your field was populated it is hard to provide more advice than that.

comment how to download the map of some cities and use it in GeoMoose?
Italy is a country, not a city. You do not mention what you have found out from your research on GeoMOOSE and offline maps so far. I suspect that Google will be the best place to do that but we do have a few GeoMOOSE Q&As here.

comment getting to grips with raster data: Tutorial needed!
Unfortunately, I think this question is in the category of "Your questions should be reasonably scoped. If you can imagine an entire book that answers your question, you’re asking too much." (see help center). As a result I am going to put it On Hold as being too broad. To get it re-opened please edit it so that it perhaps focuses on a specific place where you are stuck when trying to work with raster data showing your research into that specific topic so far.

comment Remove a layer from TOC in my printed PDF?
This "answer" seems to be related to the "question" but it appears that asker Monty and answerer user45498 may be the same person. Unfortunately, I am unable to append the answer into the question. To avoid further confusion please ask to have your user accounts merged by using these instructions.

comment python application extension onCreateFeature
Would you be able to use the content of your comment to expand upon your answer that the system has flagged as being of low quality due to its brevity, please? I recommend always treating "about a paragraph" being a minimum length answer (or question).

comment Why can't I use AddField_management in ArcPy?
Please always copy code and errors in as text rather than pictures so that they can be searched for. Having a picture as well sometimes helps but when it is only a picture an opportunity for additional learnings by future visitors is lost.

Please be aware that you posted this to Meta GIS SE rather than the main site. I will close it here and migrate it there.

comment Edit attribute table for shapefiles in folders and subfolders with arcpy?
I recommend investigating arcpy.mapping (in particular ListLayers) and arcpy.da.Walk both here and in the ArcGIS Help.

comment Geoserver (automatic labeling generalization)
Welcome to GIS SE! As a new user I recommend taking the Tour to see that this Q&A site works quite differently to (and I think much better than) discussion forums and other Q&A sites. At the moment your question is far too broad and we will need you to edit it to try and focus it down to a single issue that has emerged from your research so far, and a description of what you have tried and precisely where you are stuck.

comment arcmap display full date
You have mentioned ArcMap in your title but nowhere in the body of your question. As a result this looks like a pure Python question and may be off-topic, and better researched/asked at Stack Overflow. Would you be able to edit it to make the connection to GIS clearer, please?

comment How to calculate the center and radius of a circle based on points
Would you be able to edit your question to include the coordinate system and units that you are trying calculate your radius in because the geographic and/or projected coordinate system(s) that you work in can make a big difference to this question and its answer(s).

comment Can one parameter choice on Python toolbox tool set Display Names of other parameters?
I must apologize for not getting back to this and accepting your answer sooner. The piece of work that I was doing my "proof of concept" for has not yet eventuated so I have only tested enough of your solution to be confident that it should work. I've just added my alternate solution as an answer even though I do not plan to use it.

comment Overlaying two raster images with no spatial reference
I think this should "just work" and be no different to the steps used to co-locate two scanned aerial photos of the same area at different times. Have you tried it and found something that does not appear to work? Can you perhaps include two images as pictures in your question to demonstrate what you may perceive to be a problem?

comment General function failure Error opening feature class in ArcGIS for Desktop?
As per the duplicate's answer I think you need to make absolutely sure that nothing else is holding a lock on that table. If you think nothing is, but the problem persists, then my inclination would be to try a reboot.

comment Avoiding No data driven pages were created error in ArcGIS for Desktop?
DDP will need a name field - I think there must be no Text fields on that polytrial feature class available to choose from so try adding and populating one. Type "Check Geometry" into the online help and you should find its tool reference quickly enough but I think it is the lack of a Name Field that is the problem here.

comment Avoiding No data driven pages were created error in ArcGIS for Desktop?
I think the next step is to run Check Geometry on that polytrial feature class, and Repair Geometry if any issues show up. Also, I notice that you have no Name Field (which seems to be required) chosen on the Setup dialog - does it work when you choose one?

"and contains features for a page creation" - is there any chance that a selection has been applied to your index layer that returned 0 records.
