python xlsxwriter創建excel 之('Exception caught in workbook destructor. Explicit close() may be required for workbook.',)

python2.7使用xlsxwriter創建excel ，不關閉xlsxwriter對象，會報錯：

Exception Exception: Exception('Exception caught in workbook destructor. Explicit close() may be required for workbook.',) in <bound method Workbook.__del__ of <xlsxwriter.workbook.Workbook object at 0x0000000002215400>> ignored

 

腳本如下：

#coding=utf-8
import xlsxwriter

#創建excel文件
workbook = xlsxwriter.Workbook('test.xlsx')
worksheet = workbook.add_worksheet('test')

報錯信息如下：

查資料才知道 一定要把xlsxwriter對象給關閉了，加上workbook.close()后,完美解決 文件創建成功，如下截圖：

 

 注：python3.6版本沒此問題，不用workbook.close()，也可以執行成功！
