openpyxl錯誤：'str'對象沒有屬性'BLACK'

Question

我想使用pythons OPENPYXL模塊在excel電子表格上設置樣式。我一直想出這個錯誤：

'str' object has no attribute 'BLACK'

基本上，我的代碼讀取從.xlsx文件已知值的列表，並把它們放入一個Python列表。我使用該列表來比較訪問表中列中的值，以確保每個單元格中的值與已知值相比是正確的。

當我嘗試使用openpyxl設置樣式時，腳本被吹掉了。出於某種原因，上面的錯誤出現了。奇怪的是，我甚至沒有在任何地方使用BLACK，並且當我嘗試設置填充時似乎錯誤。在腳本的SearchCursor部分中，它遍歷每一行。第二遍，劇本爆發了。我有一種感覺，它想覆蓋一些東西，但我無法弄清楚什麼。

import openpyxl, arcpy 
from arcpy import env 
from openpyxl import Workbook 

env.workspace = r"Z:\Access_Tables\Access_Table.gdb" 

TableList = [] 
for row in arcpy.SearchCursor(r"Z:\Domains\Domains.xlsx\DOMAINS$"): 
    TableList.append(row.Code) 


# Create workbook for report. Openpyxl 
workbook = openpyxl.Workbook() 
ws = workbook.get_active_sheet() 
ws.title = "Test" 
workbook.remove_sheet(ws) 

# List out the access tables in the workspace 
for fc in arcpy.ListFeatureClasses(): 

    # Processing SOIL Point access table 
    if fc == "SOIL": 

     # List the column headings from the access table to be applied to the .xlsx table 
     fieldnames = [f.name for f in arcpy.ListFields(fc)]  
     # Create Sheet. Openpyxl 
     new_sheet = workbook.create_sheet(None,fc) 

     dictFieldnames = {} 
     for num,fname in enumerate(fieldnames): 
      dictFieldnames[num] = fname

       if not row.SOIL or len(row.SOIL.strip()) == 0: 

        # Openpyxl write. Set fill and color for cell. Write the unique id to the cell. 
        new_sheet.cell(None,x,fieldKey).style.fill.fill_type = openpyxl.style.Fill.FILL_SOLID

        new_sheet.cell(None,x,fieldKey).value = row.OBJECTID 
        x += 1 
        print 'first' 
       elif len(row.INCLUSION_TYPE) not in range(2,5): 


        # Openpyxl write. Set fill and color for cell. Write the unique id to the cell. 
        new_sheet.cell(None,x,fieldKey).style.fill.fill_type = openpyxl.style.Fill.FILL_SOLID

        new_sheet.cell(None,x,fieldKey).value = row.OBJECTID       
        x += 1 
        print 'third' 

       print x

問題是行中存在定義顏色的問題。只需將顏色分配給style.fill.start_color.index即可。例如：

new_sheet.cell(None,x,fieldKey).style.fill.start_color.index = 'FF808000' 

代替：

new_sheet.cell(None,x,fieldKey).style.fill.start_color.index = openpyxl.style.Color = 'FF808000'
