Trying to used arcpy and ddp to make a series of pdfs (or one large pdf) that displays five different layers turned on and off for each index feature.

I have found serveral different codes that all could be helpful, but I'm having toruble putting them together.

import arcpy, os

#Specify output path and final output PDF
outPath = r�?�C:MyProjectoutput\�?�
finalPdf = arcpy.mapping.PDFDocumentCreate(outPath + �??ParcelReport.pdf�?�)

#Specify the map document and the data frame
mxd = arcpy.mapping.MapDocument(r�?�C:MyProjectMyParcelMap.mxd�?�)
df = arcpy.mapping.ListDataFrames(mxd, �??Layers�?�)[0]

#Select a parcel using the LocAddress attribute and zoom to selected
parcelLayer = arcpy.mapping.ListLayers(mxd, �??Parcels�?�, df)[0]
arcpy.SelectLayerByAttribute_management(parcelLayer, �??NEW_SELECTION�?�, �??�?�LocAddress�?� = �??519 Main St�??�?�)

#Turn on visibility for each theme and export the page
lyrList = ["Soils", "Floodplains", "Zones"]
for lyrName in lyrList:
     lyr = arcpy.mapping.ListLayers(mxd, lyrName, df)[0]
     lyr.visible = True

     #Export each theme to a temporary PDF and append to the final PDF
     tmpPdf = outPath + lyrName + �??_temp.pdf�?�
     if os.path.exists(tmpPdf):
     arcpy.mapping.ExportToPDF(mxd, tmpPdf)
     #Turn off layer visibility and clean up for next pass through the loop
     lyr.visible = False
     del lyr, tmpPdf
del mxd, df, finalPdf

Will this loop through all the index features in my map?
