NameError: name 'finalPdf' is not defined

Question

Could you please help me with this error:

Traceback (most recent call last): File "C:\DDPeX\Export_GroupPDF.py", line 19, in finalPdf.appendPages(tempPdf) NameError: name 'finalPdf' is not defined Failed to execute (CFAsGroupDDP).

import arcpy
import os
mxd = arcpy.mapping.MapDocument("CURRENT")
output_folder = arcpy.GetParameterAsText(0)
ddp_lyr = mxd.dataDrivenPages.indexLayer
pdf_field = "CFA"

#Get a list of unique values to group by
pdf_list = set([row[0] for row in arcpy.da.SearchCursor(ddp_lyr,pdf_field)])

for pdfName in pdf_list:
    finalPdf = arcpy.mapping.PDFDocumentCreate(os.path.join(output_folder,pdfName + ".pdf"))
    for i in range(1, mxd.dataDrivenPages.pageCount + 1):
        mxd.dataDrivenPages.currentPageID = i
        cur = str(mxd.dataDrivenPages.pageRow.getValue(pdf_field))
        if cur == pdfName:
            tempPdf = os.path.join(output_folder,"temp_" + cur + str(i) + ".pdf")
            arcpy.mapping.ExportToPDF(mxd, tempPdf)
            finalPdf.appendPages(tempPdf)
            os.remove(tempPdf)
            finalPdf.saveAndClose()
            del finalPdf, tempPdf

Answer 1

You are deleting your finalPdf before you finishing looping through the data driven pages. Move the delete statement to the same level as the range loop.

for i in range(....):
   #do stuff

del finalPdf
