Python XLSXwriter错误。 工作簿不正确closures

我正在尝试使用模块xlsxwriter从列表中生成一个excel工作表，但是我不断收到工作簿不会closures的错误。 这里是错误信息和代码。 该列表正确生成数据。

码：

import csv import xlsxwriter f = open('alerts2.csv') csv_f = csv.reader(f) li1 = [] header = next(csv_f) for row in csv_f: # li1.append(row[5]) # li1.append(row[0]) severity = int(row[0]) #Has The the integer value from 10 - 40 if severity != 40: continue Status = str(row[1]) PolicyName = str(row[2]) PolicyBlockName = str(row[3]) PolicyRuleName = str(row[4]) Summary = str(row[5]) li1.append(severity) li1.append(Summary) # string variables print li1 f.close() print len(li1) #creating a workbook and a worksheet workbook = xlsxwriter.Workbook('results_stuff.xlsx') worksheet = workbook.add_worksheet() #initializing variables called row and columns for inputting row = 0 col = 0 #forloop iteration over the data and writing it in row by row for severity_level, summary_description in (li1): worksheet.write(row, col, severity_level) worksheet.write(row, col +1, summary_description) row += 1 workbook.close() 

错误信息：

Explicit close() may be required for workbook.',) in <bound method Workbook.__del__ of <xlsxwriter.workbook.Workbook object at 0x1054fefd0>> ignored
