python - ValueError：列集合中已存在名称“主题标识 [Individual/Pool]”。参数名称：值

问题描述

下面的代码返回一个错误：我没有发现这个错误谷歌搜索.. 

import datetime
from Spotfire.Dxp.Data import IndexSet
from Spotfire.Dxp.Data import RowSelection
from Spotfire.Dxp.Data import IndexSet, DataValueCursor, RowSelection
from Spotfire.Dxp.Data.DataType import DateTime

dictTable = Document.Data.Tables['Column renaming mapping']
dictionary = dict()
key = 0
value = 0
colNum = 0
cursorKeys = DataValueCursor.CreateFormatted(dictTable.Columns['PDW short name'])
cursorValues = DataValueCursor.CreateFormatted(dictTable.Columns['PDW long name'])
rowCount = dictTable.RowCount
rowsToInclude = IndexSet(rowCount,True)

for row in dictTable.GetRows(rowsToInclude,cursorKeys,cursorValues):

    rowIndex = row.Index
    key =   cursorKeys.CurrentValue
    print key
    val    = cursorValues.CurrentValue
    print val
    dictionary[key] = val

for table in Document.Data.Tables:

    for col in table.Columns:

        if col.Name in dictionary:
            col.Name = dictionary[key]

当然我做错了什么。我的目标是遍历所有表并修改某些列的命名。我希望它们按照我称为 discTable 的表进行修改。

根据代码生成的内容添加完整错误和打印结果。

解决方案

如果您尝试将列重命名为表中已使用的列（给定表中的 2 列不能具有相同的名称），您将收到此错误。我建议找出导致错误的表并仔细检查是否还没有名为“主题标识 [个人/池]”的列

谢谢，杰克！
