錯誤在Xlrd模塊

Question

道歉爲我的長描述。我沒有任何選擇...

基本上，我已經寫了一個XML解析器在python中。它從XML標記中提取數據並使用xlsxwriter模塊將數據寫入Excel工作表。一旦創建了Excel工作表，我使用xlrd包在Excel中讀取數據，處理數據，然後根據結果列中相同的Excel中的條件更新我的結果。現在，我的問題是，當Excel已經創建並出現在路徑中我的程序工作正常，但是當我刪除Excel並運行該程序時，它會拋出如下錯誤：

Traceback（最近一次調用最後）：

File "AMS_parse.py", line 71, in <module> 
rworkbook = xlrd.open_workbook('AMS.xlsx') 
File "C:\Python27\lib\site-packages\xlrd\__init__.py", line 394, 
    in open_workbook 
f = open(filename, "rb") 
IOError: [Errno 2] No such file or directory: 'AMS.xlsx'

我的程序如下：

format = workbook.add_format({'bold': 25,'font_color': 'green'}) 
worksheet.write('A1','Component',format) 
worksheet.write('B1','DataType',format) 
worksheet.write('C1','PrivateData',format) 
worksheet.write('D1','Result',format) 
worksheet.set_column('A:A', 15)

#Close the work book after writing 
try: 
    workbook.close() 
except: 
    # Handle your exception here. 
    print("please close the AMS.xlsx file") 

請扔在如何糾正錯誤的一些情況。

您需要先關閉workbook，然後再打開rworkbook。 事實上，你不應該使用讀卡器，直接在workbook進行計算。
