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.

comment Programmatically adding .shp file to .mxd file
I'll re-open this question to see if anyone will post an Answer. I'll try to get back and test it - for some reason I thought you were using 10.0 but it seems to be 10.2 so I must have misread.

As a test can you close ArcMap and try this again. Can you capture a screenshot of your Data Driven Pages Setup and include that in your question if you see the same error again, please/

comment Programmatically adding .shp file to .mxd file
Placing a shapefile in "C:/Python27/ArcGISx6410.2" seems like a very risky thing to do - try copying it to a simple location like C:\temp as a test. Also, what is your precise operating system? It sounds like you may need to double-check your configuration against the System Requirements for 10.0.

comment Programmatically adding .shp file to .mxd file
Your current code snippet does not include setting your workspace via arcpy.env.workspace prior to trying to use a shapefile from it without the full path being specified. Unfortunately, I do not have 10.0 to test your code.

comment Programmatically adding .shp file to .mxd file
What precise code did you run? What precisely was the error you received from that code? In your question I can only see you trying the other way.

comment Programmatically adding .shp file to .mxd file
This answer from the duplicate has the technique that I think should work at 10.0 - gis.stackexchange.com/a/12538. I think the one you are trying had a bug that was fixed at 10.1 SP1.

comment Pricing for ArcGIS for Server 10.3 and Portal for ArcGIS?
SE encourages the Q&A to take place here rather than via emails so that the information helps later visitors to the site and so your email address will be removed too. However, you should feel free to include that, and anything else you wish in your user card. I will do my best to maintain your good intentions as I perform my edit but if I do not get that "right" then there is an edit button beneath your answer to tweak it some more.

Welcome to GIS SE! This may seem strict but the GIS SE instruction is to remove signatures (which I will do to your answer) because every question, answer or comment you post here is already signed by your user card.

comment How can I refer to two tables in ArcPy's CalculateField_management?
Could you please include your Python code snippet within your question where it can be nicely formatted using the {} button. When you say "I linked the c's helysz field to the secondly created table's hely field", do you mean that you used ArcMap to apply a Join between them, or did you use the AddJoin tool, or something else?

comment How to read offline map in GeoMOOSE?
Welcome to GIS SE! As a new user I recommend that you take our Tour where you will see that we think it important that there is only one question per question. To prevent your question being placed on hold would you be able to edit it to focus on just the most important of your three questions, please?

comment Where to find more detail on algorithms used in ArcGIS Desktop's location allocation solver?
I am only speculating - if the algorithm came out of other than internal R&D then I find Esri is unusually open for a commercial enterprise and may well share it.
