I am trying to get an user input for getting a parcel name and pan the map to that selection. What am I doing wrong in the code below?

import arcpy

#Msg box to get parcel Name
parcel_Name = str(arcpy.GetParameterAsText(0))
arcpy.AddMessage ("Loading parcel " + parcel_Name)

try:

    mxd = arcpy.mapping.MapDocument('CURRENT')
    df = arcpy.mapping.ListDataFrames(mxd, "Layers") [0]
    ssparcel = arcpy.mapping.ListLayers(mapDoc, "ssparcel", df)[0]

    whereClause = "Name ='%s'" % parcel_Name
    arcpy.SelectLayerByAttribute_management(ssparcel, "NEW_SELECTION", whereClause)
    df.extent = df.panToExtent(ssparcel.getSelectedExtent())
        #df.scale *= 1.5
    arcpy.RefreshActiveView()

except:

    arcpy.AddWarning ("Error")

...

Removed the "try" and got the following error:

Executing: Script "0002" Start Time: Thu Jun 05 11:32:14 2014 Running script Script... IndentationError: unexpected indent (abcd.py, line 9) Failed to execute (Script). Failed at Thu Jun 05 11:32:14 2014 (Elapsed Time: 0.00 seconds)

  • Can you pull the code out of the try/except block so you can get the actual error being raised and add it to your question? – Jason Scheirer Jun 5 '14 at 18:09
  • The Indentation Error is occurring if you removed the Try but did not remove the indentations. Python needs all of the code properly indented to work. – Dan Jun 5 '14 at 18:50

The following worked for me in the Python window:

mxd = arcpy.mapping.MapDocument("current")
df = arcpy.mapping.ListDataFrames(mxd)[0]
lyr = arcpy.mapping.ListLayers(mxd, "Prog*", df)[0]
arcpy.SelectLayerByAttribute_management(lyr, "NEW_SELECTION", "OBJECTID=1")
df.panToExtent(lyr.getSelectedExtent())
arcpy.RefreshActiveView()

Or, the last two lines can be combined as (like you did):

df.extent = df.panToExtent(lyr.getSelectedExtent())

EDIT: The difference I see with yours is the variable mapDoc.

How do I pass a string parameter obtained from user like "OBJECTID="&userinput?
