python-异常(‘工作簿析构函数中捕获了异常.工作簿可能需要显式close().’

在Oracle Linux 6.6中运行Python程序时,出现以下异常.
我正在使用Python版本2.6.

Exception(‘Exception caught in workbook destructor. Explicit close()
may be required for workbook.’

我的代码是：

#from xlrd import open_workbook
import numbers, string
import xlsxwriter

#import xlwt
import datetime as dt
import email.mime.application

from xlsxwriter import Workbook   

curtme = datetime.datetime.strftime(datetime.datetime.now(), '%Y-%m-%d_%H:%M:%S')
workbook = xlsxwriter.Workbook('/Export/Report_'+curtme+'.xlsx')
worksheet = workbook.add_worksheet()
completed_fmt = workbook.add_format({'bold': True, 'border': 6,'align': 'center','valign': 'vcenter','bg_color': 'yellow','font_size':'12', 'font_name':'Calibri'})
worksheet.set_column(0,9,36)
worksheet.merge_range('A2:C6',None, None)
worksheet.merge_range('A2:C6',None, None)
cellformat = workbook.add_format({'bold': True, 'border': 6,'align': 'center','valign': 'vcenter','font_size':'16', 'font_name':'Calibri'})
cellfmt = workbook.add_format({'bold': False, 'border': 6,'align': 'center','valign': 'vcenter','font_size':'12', 'font_name':'Calibri'})
worksheet.insert_image('A1', 'Image/logo.jpg')
worksheet.merge_range('B1:C6', "Report", cellformat)
    rowx = 6
    for colx, value in enumerate(headings):
            worksheet.write(rowx, colx, value, completed_fmt)
            i=1
            for i, row in enumerate(myresult):
                    for j, col in enumerate(row):
                            worksheet.write(i+7, j, col,cellfmt)
    workbook.close()
db.close()

解决方法:

异常表明可能需要close().这是为了捕获xlsxwriter异常(其中隐式关闭不足).

由于close()已包含在您的程序中,因此不是异常的来源.

实际错误将在堆栈跟踪中位于其上方.一些潜在的问题：

>缩进是错误的.
>标题未定义.
>未定义myresult.
