Python - help with GetMessage

MarkWisniewski — Wed, 15 Apr 2015 09:08:48 GMT

Hi,

I am after a way on using arcpy.GetMessage to achieve the following message in the geoprocessing dialog result window?;

The above 4 datasets have been reprojected to: WGS Web Mercator (auxiliary sphere) and saved in S:\GisData

Does anybody know this can be achieved?

Do you mean arcpy.AddMessage('some message... ')?

GetMessages documentation....for recording errors

GetMessage documentation ... for geoprocessing services if there are any messages

Within there are a bunch of other message types.

AddMessage is needed to add 'stuff' which can be retrieved by any of the 'Gets...

Trying to do this, which I cant get arcpy.Message(fc) and arcpy.Message(msg) to display results in dialog window.

#Loop through shapfiles in folder and reproject
 for fc in fcList:
  fcspatialRef = arcpy.Describe(fc).spatialReference.name
   if fcspatialRef != spatialRef:
  arcpy.Project_management(fc, outFolder + "\\" + fc, template)
  projCount = int(arcpy.GetCount_management(fc).getOutput(0))
   else:
  arcpy.CopyFeatures_management(fc, outFolder + "\\" + fc)

# Print shapefile Project results
  arcpy.AddMessage(fc)
# Get the count from GetCount's Result object
 msg = "{0} datasets have been reprojected to: {1} and saved in {2}".format(projCount, spatialRef, OutFolder)
 arcpy.AddMessage(msg)

That's not very informative. What does "cant get it to work" mean exactly? Do you get an unexpected result, do you get an error message, does python crash, does your PC crash, does your PC spontaneously combust and let all the magic smoke out?

Just kidding, what was the error message/unexpected result?

PS: you are setting projCount to the number of features in the last fc that you reproject. If you want to print the number of fcs that you reprojected, you need to do something like:

projCount = 0
for fc in fcList:

    etc...
    if fcspatialRef != spatialRef:

        arcpy.Project_management(fc, outFolder + "\\" + fc,template)
        projCount += 1 #or projCount = projCount + 1

Hi Ernst, besides including the actual error message in your reply as Luke suggested, it would help if you put you code in a formatted code block for Python, like is shown in Luke's reply. Python is very picky on the indentation, and a straight copy/past tends to mess is up, making it hard for others to know whether indentation is causing you an issue or if there is some other issue. there is a good how-to Posting Code blocks in the new GeoNet It's a very quick read, and since you seem to be getting into Python quick a bit this past week, it's worth getting in the habit since it would help others help you. Main things, you have to be responding from the thread, not from within your inbox, so you can see the "Use Advanced Editor". Good luck, and I hope you get you problem resolved.
