Thanks for this post, I'm sure this information will come in handy for quite a few people. For those wishing to get started with less hassle, there are pre-built binaries already available at http://www.lfd.uci.edu/~gohlke/pythonlibs/#pycuda ... View more

Python does support the degree symbol, that \x00 sequence you're seeing is the escaped version of the string so that it will work in ASCII. You're safer using a unicode object with an escaped character. Sets will not work here, Python sets are unordered meaning you can only assume that all the elements will be there, but when asking for them you will get them back in an arbitrary manner. You can use zip to unify two lists in the way you're looking for. I would rewrite the script like this: symbols = (u'\u00b0', u"'", u"''") Update_cursor = arcpy.UpdateCursor(feature_class) for rows in update cursor:     coord = row.latitude     merged_items = zip(coord.split(u"-"), symbols)     merged_value = "".join(x + y for (x, y) in merged_items)     row.new_field = merged_value     Update_cursor.updateRow(row) The 'u' in front of the quotes signifies it's a unicode object -- this gives you more predictable behavior when working with extended characters. Then zip gives you a list of tuples of the form [(num1, sym1), (num2, sym2), (num3, sym3)]. Then you add each of the two items together into a single string, leaving you with a list of string, and then join each of those together into a single string. ... View more

I don't think this is an event loop problem at all, no even loop is spun up just by importing arcpy (however, there is an event loop running in ArcMap and friends that WILL conflict with the easygui event loop). This looks like a locale issue -- try setting your locale to English - US in ArcGIS administrator under the Advanced... button and see if this still is an issue. If so, try using python's locale module to reset the locale to en_US after importing arcpy. ... View more

You need to save the MXD when you're done. import arcpy, os mxd = arcpy.mapping.MapDocument("M:/nih/AsbestosAbatement/Floorplans/BLDG_6A/Floorplanpdf.mxd") for lyr in arcpy.mapping.ListLayers(mxd, "BuildingFloorLines"):     layer.definitionQuery = "[FLR] = '02'" mxd.save() print 2 If you're currently in arcmap and want to act on the active map: import arcpy, os mxd = arcpy.mapping.MapDocument("current") for lyr in arcpy.mapping.ListLayers(mxd, "BuildingFloorLines"):     layer.definitionQuery = "[FLR] = '02'" arcpy.RefreshActiveView() arcpy.RefreshTOC() print 2 ...

Do not change the active data frame in Geoprocessing scripts. Before a geoprocessing tool runs, it takes a snapshot of the active data frame's layers, and then restores it when it finishes executing. By changing the active data frame in between the snapshot and the restore, it gets into a confused state and may drop layers. ... View more
