Through a plethora of trials and research, I finally was able to get a script to work.
My original question encompassed me needing to take an .mxd and create a PDF mapbook document that will contain a map for each county in the counties FC. Then, I needed to change the title of each map to the name of the county being shown. Lastly, I need to scale the map a bit so it shows an area just a bit larger than the actual extent.
The following script works great. I hope this will help others in the future;
import arcpy, os from arcpy.mapping import * countiesPath = "C:\\Data\\COUNTIES.shp" pdfPath = "C:\\Data\\COCounties.pdf" mxdPath = "C:\\Data\\Counties.mxd" mxd = MapDocument(mxdPath) dataFrame = (mxdPath, "COUNTIES") listLayers = ListLayers(mxd) finalPDF = PDFDocumentCreate(pdfPath) df = ListDataFrames(mxd, "Layers") for layer in listLayers: if layer.name == "COUNTIES" : with arcpy.da.SearchCursor(layer, "COUNTY") as cursor: for row in cursor: countyName = row whereClause = "COUNTY='"+ countyName + "'" arcpy.SelectLayerByAttribute_management(layer, "NEW_SELECTION", whereClause) df.zoomToSelectedFeatures() arcpy.SelectLayerByAttribute_management(layer,"CLEAR_SELECTION") df.scale *= 1.5 titleItem = ListLayoutElements(mxd, "TEXT_ELEMENT", "title") titleItem.text = "Map of: " + countyName + " COUNTY" countyPDF=r"C:\\Data"+countyName+".pdf" ExportToPDF(mxd,countyPDF,"PAGE_LAYOUT",resolution=600,df_export_width=1100,df_export_height =800) finalPDF.appendPages(countyPDF) os.remove(countyPDF) finalPDF.saveAndClose() del finalPDF del mxd
