I am attempting to export a set of maps using python and data driven pages. I have been successful in getting the code to work but I am struggling with the file naming of the exported JPEG's. I need to the file names to coincide with a field in the attribute table. Basically I am making a set of parcel maps, and need the file name to be the parcel number (PARCEL_NO). Here is the code I am using. I am a novice when it comes to this stuff so please be patient. Thanks in advance!
mxd = arcpy.mapping.MapDocument("CURRENT")
for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):
mxd.dataDrivenPages.currentPageID = pageNum
arcpy.mapping.ExportToJPEG(mxd, r"P:\Township Maps\Bloomingdale\JPEG" + str(pagename) + ".jpeg")
del mxd
mxd = arcpy.mapping.MapDocument("CURRENT")
for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):
mxd.dataDrivenPages.currentPageID = pageNum
arcpy.mapping.ExportToJPEG(mxd, r"P:\Township Maps\Bloomingdale\JPEG" + str(pagename) + ".jpeg")
del mxd
