Logan good suggestion...and you need not even comment out the print statement, in fact you could get ready for python 3.0 by adding these blocks     try        print strMessage     #pre 3.0     except        print (strMessage)   #3.0 +     gp.AddMessage(strMessage) the print statement will simply become heat energy if gp is being used and vica versa. ...

Frank...unfortunately it doesn't print to other IDE's output...don't use console...too dark and gloomy and reminds me of the old DOS days ... View more

It just needs to be present on the computer.  It need not be running but arcpy needs to be imported which means it must be on the computer.  gp.Addmessage statements need to be replaced with print statements.  The following is an example ''' CreatePolyDemo.py Demonstrates calculating various properties for polygons ''' import arcpy pnt = arcpy.Point() triangle = [[0,0],[0,1],[1,0]] square = [[0,0],[0,1],[1,1],[1,0]] rectangle = [[0,0],[0,1],[2,1],[2,0]] polygons = [triangle, square, rectangle] labels = ["Triangle", "Square", "Rectangle"] array = arcpy.Array() polys = [] for i in range(len(polygons)):   a_poly = polygons   print "\n", labels," Coordinates: ", a_poly   for pair in a_poly:     pnt.X = pair[0]     pnt.Y = pair[1]     array.add(pnt)     print " X %20.16f  Y %20.16f" % (pnt.X, pnt.Y)   array.add(array.getObject(0))   poly = arcpy.Polygon(array)   print "Polygon properties:"   print " area %20.16f\n length %s" % (poly.area, poly.length)   print " centroid %s\n true centroid %s " % (poly.centroid, poly.trueCentroid)   print " first point %s\n last point %s " % (poly.firstPoint, poly.lastPoint)   print " extent %s " % (poly.extent)   print " hull %s\n " % (poly.hullRectangle)   array.removeAll()   polys.append(poly) ...

Ted and see that roughly 75% want one, that counts for something, and there are 2 people against that are from Esri. So, whether Esri gets a vote, either keeps as is or the 75% goes up. No one who has comments, except for JB works for ESRI so I would suspect that any voting is from the users, myself included. Also, it is the NON-vote that is more important, should we treat those as abstaining from the issue or should we cast them into the pile to leave things as they are???  Those figures suggest a different outcome. ...

as of Nov 1, 491 view, 31 votes...what is up?  an indication of the confusion/lack of interest...kill General Anything... and make people commit to a forum thread...geoprocessing is geoprocessing not mapping or spatial analyst etc etc..  Import arcpy from Pythonwin or you favourite IDE, SA is there, so is the mapping stuff...I don't want to have a specific Python forum if it is going to be filled with SA stuff, since it should be in the SA forum...since SA is the issue/focus and Python is only ONE of the solutions. Sorry...I feel like I am backing up over the deer to finish off this thread (hunting season here).  The ball is in the "JB court"... ... View more
