Having trouble getting my code to work. Keep getting IOError that my parks.shp doesn't exist....not sure I understand what this is saying.

import arcpy mxd = "D:\...\TravisCountyAustinTxx.mxd" mapdoc = arcpy.mapping.MapDocument(mxd) dataset = "D:\...\TravisCountyAustinTxx.mxd\parks.shp" spatialref = arcpy.Describe(dataset).spatialReference extent = arcpy.Describe(dataset).extent for df in arcpy.mapping.ListDataFrames(mapdoc): df.spatialReference = spatialref df.panToExtent() df.scale = 15000 print "\nData frame " + df.name + " contains the following layers:" lyrlist = arcpy.mapping.ListLayers(mapdoc, "", "", df) for lyr in lyrlist: print lyr.names mapdoc.save() del mapdoc

Full error message:

File "D:\Python27\ArcGIS10.2\Lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 325, in RunScript exec codeObject in main.dict File "D:\CLASSES\Debugging_andErrorHandlingLab\Scripts\Mod3_Script2_Template (2).py", line 12, in spatialref = arcpy.Describe(dataset).spatialReference File "C:\Program Files (x86)\ArcGIS\Desktop10.2\arcpy\arcpy__init__.py", line 1234, in Describe return gp.describe(value) File "C:\Program Files (x86)\ArcGIS\Desktop10.2\arcpy\arcpy\geoprocessing_base.py", line 374, in describe self._gp.Describe(*gp_fixargs(args, True))) IOError: "D:\CLASSES\Debugging_andErrorHandlingLab\Data\TravisCountyAustinTxx.mxd\parks.shp" does not exist

  • Please review the code, since the last line seems mashed up Commented Jul 19, 2016 at 14:49

    Your problem is likely the failure to either escape backslashes or to use "raw" mode (prepend an 'r' before the quote). So Python is correct -- the file "\...\TravisCountyAustinTxx.mxd\parks.shp" does not exist in directory "D:" Commented Jul 19, 2016 at 14:52
  • Code blocks must have FOUR leading spaces. There's a {} button to format it for you. Commented Jul 19, 2016 at 14:53
  • I tried the use r"D......shp" as well. No luck. The full error message is to follow. Commented Jul 19, 2016 at 14:56

    Thank you for including the full error. Now look at what it says. An MXD is a file. No shapefile will be inside it as if it were a directory. Commented Jul 19, 2016 at 15:01

LOTS OF ERRORS were fixed --.spatialRefernce (no good) .extent(no good), lyrlist, had too many arguments--FIXED

import arcpy mxd = r"D:\CLASSES\Debugging_andErrorHandlingLab\Data\TravisCountyAustinTxx.mxd" mapdoc = arcpy.mapping.MapDocument(mxd) dataset = r"D:\CLASSES\Debugging_andErrorHandlingLab\Data\TravisCountyAustinTxx.mxd" spatialref = arcpy.Describe(dataset) extent = arcpy.Describe(dataset) df.scale = 15000 print "\nData frame " + df.name + " contains the following layers:" lyrlist = arcpy.mapping.ListLayers(mapdoc, "", df) for lyr in lyrlist: print lyr.name for df in arcpy.mapping.ListDataFrames(mapdoc): df.panToExtent(df.extent) mapdoc.save() del mapdoc

Locate your shapefile.

The error message says it's in:

"D:\CLASSES\Debugging_andErrorHandlingLab\Data\TravisCountyAustinTxx.mxd\parks.shp"

The .MXD can't be a folder, so it's definitely not there.

Perhaps it's in the same folder as the MXD:

dataset = r"D:\CLASSES\Debugging_andErrorHandlingLab\Data\parks.shp"
