Python, Describe.spatialReference errors

Question

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

• Vince: Please review the code, since the last line seems mashed up
• Vince: 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:"
• Vince: Code blocks must have FOUR leading spaces. There's a {} button to format it for you.
• Petunia311: I tried the use r"D......shp" as well. No luck. The full error message is to follow.
• Vince: 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.

Answer 1

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

Answer 2

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"
