mxd.dataDrivenPages.pageRow.setValue() doesn't work

Dazzling — Wed, 24 Apr 2024 09:51:44 GMT

I'd like to write a Python script to help me deal with making illustrations that are filtered by some number in each layer, and then I want DataDrivenPages to zoom into the corresponding view. However, I have encountered an error as follows:

I have checked the document about 'pageRow', and I knew it was read-only, but it could then be read and/or modified as necessary. But I don't know why this code cannot work.

This is the code:

import arcpy import arcpy.mapping as mapping import xlrd work_book = xlrd.open_workbook(r'C:\Users\39470\Desktop\schedule.xls') size = work_book.sheets()[0].nrows kqbh, kqmc = [], [] for i in range(1, size): kqmc.append(work_book.sheets()[0].row(i)[2].value) kqbh.append(work_book.sheets()[0].row(i)[3].value) mxd = mapping.MapDocument('CURRENT') layers = mapping.ListLayers(mxd) for number, name in zip(kqbh, kqmc): if number != '': mxd.dataDrivenPages.pageRow.setValue('KQBH', number) for lyr in layers: if lyr.isFeatureLayer: if lyr.symbologyType == 'UNIQUE_VALUES': sym = lyr.symbology df = mapping.ListDataFrames(mxd)[0] sym.valueField = 'KQBH' sym.classValues = [number] sym.classLabels = [lyr.name] sym.showOtherValues = False arcpy.RefreshActiveView() arcpy.RefreshTOC() mxd.saveACopy(r'C:\Users\39470\Desktop\illustrations\\' + name + '.mxd')

Can anyone help me?

Thanks!
