Python - help with GetMessage

MarkWisniewski

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?

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
<SPAN class="kwd">for</SPAN><SPAN class="pln"> fc </SPAN><SPAN class="kwd">in</SPAN><SPAN class="pln"> fcList</SPAN><SPAN class="pun">:</SPAN><SPAN class="pln">
</SPAN>
    etc...
    <SPAN class="kwd">if</SPAN><SPAN class="pln"> fcspatialRef </SPAN><SPAN class="pun">!=</SPAN><SPAN class="pln"> spatialRef</SPAN><SPAN class="pun">:</SPAN><SPAN class="pln">
</SPAN>
        <SPAN class="pln">arcpy</SPAN><SPAN class="pun">.</SPAN><SPAN class="typ">Project_management</SPAN><SPAN class="pun">(</SPAN><SPAN class="pln">fc</SPAN><SPAN class="pun">,</SPAN><SPAN class="pln"> outFolder </SPAN><SPAN class="pun">+</SPAN><SPAN class="pln"> </SPAN><SPAN class="str">"\\"</SPAN><SPAN class="pln"> </SPAN><SPAN class="pun">+</SPAN><SPAN class="pln"> fc</SPAN><SPAN class="pun">,template)</SPAN><SPAN class="pln"></SPAN>
        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.

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