Here is an example on how to do this.  The code uses the Summary Statistics tool to summarize the Area field in each polygon feature class within feature datasets, then writes the feature class name and Area sum to a previously created table. import arcpy from arcpy import env env.overwriteOutput = True env.workspace = r"C:\MapsandGeodatabase\LocalGovernment.gdb" arcpy.CreateTable_management(env.workspace, "AREA_SUM") arcpy.AddField_management("AREA_SUM", "Name", "Text", "75") arcpy.AddField_management("AREA_SUM", "SUM_Shape_Area", "Double") for dataset in arcpy.ListDatasets("*"):     lstFCs = arcpy.ListFeatureClasses("*", "", dataset)     for fc in lstFCs:         desc = arcpy.Describe(fc)         if desc.shapeType == "Polygon":             rows = arcpy.InsertCursor("AREA_SUM")             row = rows.newRow()             row.Name = fc             sumArea = arcpy.Statistics_analysis(fc, "Stats", [["Shape_Area", "SUM"]])             rows2 = arcpy.SearchCursor(sumArea)             for row2 in rows2:                 totArea = row2.getValue("SUM_Shape_Area")             row.SUM_Shape_Area = totArea             rows.insertRow(row)             totArea = 0 del row, rows, row2, rows2 arcpy.Delete_management("Stats") ...

You could do this using a 'while' loop.  Ex: x = 4 while x < 10:     lstRasters = gp.ListRasters("*" + str(x))     for raster in lstRasters:         print raster     x += 1 ... View more

Sorry for the misunderstanding.  Here is an example on how to change the layer names: import arcpy, os from arcpy import env from arcpy import mapping env.workspace = r"C:\temp\python" env.overwriteOutput = True for (path, dirs, files) in os.walk(env.workspace):     for file in files:         if ".mxd" in file.lower():             mxd = os.path.join(path, file)             mxd = mapping.MapDocument(mxd)             for df in mapping.ListDataFrames(mxd, "*"):                 for lyr in mapping.ListLayers(mxd, "*", df):                     if " " in lyr.name:                         lyr.name = lyr.name.replace(" ", "")                 for lyr in mapping.ListLayers(mxd, "*", df):                     if "," in lyr.name:                         lyr.name = lyr.name.replace(",", "")             mxd.save()             del mxd ...

Here is an example on how to do this: import os workspace = r"C:\temp\python" for (path, dirs, files) in os.walk(workspace):     for file in files:         if ".mxd" in file.lower():             if "," in file:                 str = os.path.join(path, file)                 new = str.replace(",", "")                 os.rename(str, new)             elif " " in file:                 str = os.path.join(path, file)                 new = str.replace(" ", "")                 os.rename(str, new) You will just need to update 'workspace = r"C:\temp\python"' with the directory that contains the MXDs.  The example above will also loop through all sub directories. ...

I would recommend migrating from Image Server to Mosaic Datasets.  You can very easily access Mosaic Datasets using arcpy.  Note:  ArcGIS 10 is the last release of Image Server. http://resources.esri.nl/downloads/ArcGIS_10_Deprecation_Plan.pdf ArcGIS 10.0 is the last release of the stand-alone ArcGIS Image Server product. This product has been replaced with the ArcGIS Server Image Extension. Any existing users of the stand-alone Image Server product or technology (using ISDef files), should plan their migration to the ArcGIS Server Image extension. Existing ArcGIS Image Server users should migrate from using ISDef file to using the Mosaic Datasets, a new data model in the geodatabase for managing collections of imagery and rasters. Mosaic Datasets are created and edited with ArcGIS Desktop (ArcEditor and ArcInfo) and published using ArcGIS Server with the Image Extension. Existing ISDef files can be added to Mosaic Datasets for conversion. ... View more

hzhu is correct.  You are specifying a shapefile rather than a feature class.  Change: inFeature = "soilmu_in.shp" to inFeature = "soilmu_in" ... View more

You can use the arcpy.mapping.ListLayers function to access the dataSource property.  Next you can append this to a list, convert the layers to the new geodatabase, and update the MXD.  Ex: import arcpy from arcpy import env from arcpy import mapping env.workspace = r"C:\temp\python" list = [] mxd = mapping.MapDocument(r"C:\temp\python\test.mxd") for df in mapping.ListDataFrames(mxd, "*"):     for layers in mapping.ListLayers(mxd, "*", df):         list.append(layers.dataSource) for n in list:     arcpy.FeatureClassToGeodatabase_conversion(n, r"C:\temp\Test2.gdb") mxd.replaceWorkspaces(r"C:\Temp\Python", "SHAPEFILE_WORKSPACE", r"C:\Temp\test2.gdb", "FILEGDB_WORKSPACE") mxd.findAndReplaceWorkspacePaths(r"C:\temp\python\test.gdb", r"C:\temp\test2.gdb") # mxd.replaceWorkspaces(r"C:\temp\python\test.gdb", "FILEGDB_WORKSPACE", r"C:\temp\python\test.gdb", "FILEGDB_WORKSPACE") mxd.saveACopy(r"C:\Temp\Project2.mxd") print "Save Successful" ...

If all your shapefiles reside in one folder, and your feature classes within a single geodatabase you can use the 'arcpy.ListFeatureClasses' function to list all shapefiles and feature classes then append them to a list. Next, you can use the 'arcpy.FeatureClassToGeodatabase_conversion' function to convert the shapefiles/feature classes to a new geodatabase. Finally, you can run the 'replaceWorkspaces' and 'replaceDataSource' methods to remap the datasources and save it as a new MXD. Ex: import arcpy, os from arcpy import env from arcpy import mapping folder = r"C:\temp\python" env.workspace = folder fcList = [] lstFCs = arcpy.ListFeatureClasses("*") for fc in lstFCs:     fcList.append(os.path.join(folder + "\\" + fc)) database = r"C:\temp\python\test.gdb" env.workspace = database lstFCs = arcpy.ListFeatureClasses("*") for fc in lstFCs:     fcList.append(database + "\\" + fc) for fc in fcList:     print fc     arcpy.FeatureClassToGeodatabase_conversion(fc, r"C:\temp\test2.gdb")     print "Successfully converted"     mxd = mapping.MapDocument(r"C:\temp\python\test.mxd") mxd.replaceWorkspaces(r"C:\Temp\Python", "SHAPEFILE_WORKSPACE", r"C:\Temp\test2.gdb", "FILEGDB_WORKSPACE") mxd.findAndReplaceWorkspacePaths(r"C:\temp\python\test.gdb", r"C:\temp\test2.gdb") mxd.saveACopy(r"C:\Temp\Project2.mxd") print "Save Successful" If your data resides in multiple folders/geodatabase I would recommend looking into the os.walk function. ...

You will need to specify which files to search for in the 'arcpy.ListFiles' function.  Also, you will need to specify the Sheet # when executing the 'arcpy.TabletoTable_conversion' tool when working with Excel files.  Ex: lstFiles = arcpy.ListFiles("*.xls") for file in lstFiles:     arcpy.TableToTable_conversion(file + "\\" + "Sheet1$", outpath, "test.dbf") ...

You can run any tool in batch.  Simply right-click on the 'Clip' tool in ArcToolbox > Data Management Tools > Raster Processing.  You will see the option 'Batch'.  Right-click under 'Input Raster' and choose 'Browse'.  You can select multiple rasters here. ... View more

Hi Amy, I looked into updating the polylines using python, but this may not be possible.  A polyline object's properties are all read-only.  Therefore I could not find a way to write new coordinate values to the end points of the mains. Something you can do to possibly help you is to write some code to obtain the OBJECTIDs of the mains that need to be moved.  This will provide you a list with the feature's end points that are not snapped to a manhole.  Ex: import arcpy from arcpy import env env.overwriteOutput = True env.workspace = r"C:\Temp\Python\test.gdb" fc = "swManhole" fc2 = "swGravityMain" pnt = arcpy.Point() # Move Manholes to GPS location rows = arcpy.UpdateCursor(fc) for row in rows:     pnt.X = row.POINT_X     pnt.Y = row.POINT_Y     row.shape = pnt     rows.updateRow(row) del row, rows # Convert Main endpoints to points feature class arcpy.FeatureVerticesToPoints_management(fc2, "Main_EndPts", "END") # Find all Main endpoints within 5 feet of manholes arcpy.Near_analysis("Main_EndPts", fc, "5") # Create a layer of all Main endpoints within 5 feet of manholes lyr = arcpy.MakeFeatureLayer_management("Main_EndPts", "Main_EndPts_Lyr", "NEAR_DIST > 0") list = [] # Append X & Y values of Main endpoints to list rows = arcpy.SearchCursor(lyr) for row in rows:     list.append(float(row.shape.centroid.X) + float(row.shape.centroid.Y)) del row, rows OBJECTIDs = [] # Find OBJECTIDs of the Mains that need to be moved rows = arcpy.SearchCursor(fc2) for row in rows:     geom = row.shape     XY = float(geom.lastPoint.X) + float(geom.lastPoint.Y)     if XY in list:         OBJECTIDs.append(row.OBJECTID) del row, rows arcpy.Delete_management("Main_EndPts") print OBJECTIDs ...

Take a look at the example script below.  Also, be sure to execute the make a feature layer before executing the 'arcpy.SelectbyAttribute_management' function. where_clause = ("Status = 'U'") arcpy.MakeFeatureLayer_management("Crimes", "Crimes_Lyr") arcpy.SelectLayerByAttribute_management("Crimes_Lyr", "NEW_SELECTION", where_clause) print arcpy.GetCount_management("Crimes_Lyr") You can also use the 'arcpy.FieldDelimiters' function to get the correct syntax of the field: fld = arcpy.AddFieldDelimiters("Crimes", "Status") where_clause = (fld + " = 'U'") arcpy.MakeFeatureLayer_management("Crimes", "Crimes_Lyr") arcpy.SelectLayerByAttribute_management("Crimes_Lyr", "NEW_SELECTION", where_clause) print arcpy.GetCount_management("Crimes_Lyr") ...
