使用 xlswriter 将日期时间添加到工作表时抛出 Python 异常

Question

我有以下抛出异常的 Python 代码，我很难理解我做错了什么：

    import xlsxwriter
    import datetime


    date = datetime.date.today()
    workbook = xlsxwriter.Workbook('datetime.xlsx')
    date_format = workbook.add_format({'num_format': 'dd mm yyyy'})
    worksheet = workbook.add_worksheet()
    worksheet.write_datetime(0, 0, date, date_format)
    workbook.close()

异常发生在

workbook.close()

，是

TypeError: must be real number, not datetime.date

。堆栈跟踪如下：

Traceback (most recent call last):
  File "scratch_4.py", line 10, in <module>
    workbook.close()

    self.fh.write("""<c%s><v>%.16G</v></c>""" % (attr, number))
                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~
TypeError: must be real number, not datetime.date

我尝试了多种不同的方法，但都失败并出现相同的异常。

事实证明，我运行代码的虚拟环境已损坏。
