脚本中的 Python 错误，但在 jupyter notebook : TypeError: 'module' object is not callable 中有效

Question

运行在变量 h 中创建假期列表的脚本时出现以下错误。我首先在 jupyter notebook 上运行脚本，它运行良好，没有错误，但是当我将它作为脚本运行时，它不起作用。

我看了几个posts解决这个问题，但我指定了我在脚本中导入的内容，所以不确定为什么它仍然不起作用。

错误

Traceback (most recent call last):
  File "\\user\config\workspace\ExcelProjects\src\root\nested\scrap.py", line 53, in <module>
h = USBankHolidayCal.holidays(datetime(2016, 1, 1), datetime(2016, 12, 31))
TypeError: 'module' object is not callable  

代码

from pandas.tseries.holiday import Holiday, AbstractHolidayCalendar, nearest_workday, MO, USFederalHolidayCalendar
from pandas.tseries.offsets import DateOffset, CDay
UKdays = []


class UKHoliday(AbstractHolidayCalendar):
rules = [
    Holiday('Boxing Day', month=12, day=26, year=2016,observance=nearest_workday),
    Holiday('Christmas Day', month=12, day=27, year=2016,observance=nearest_workday),
    Holiday('New Years Day', month=1, day=2, observance=nearest_workday),
    Holiday('Good Friday', month=4, day=14, observance=nearest_workday),
    Holiday('Easter Monday', month=4, day=17, observance=nearest_workday),
    Holiday('Early May', month=5, day=1, observance=nearest_workday),
    Holiday('Spring Bank', month=5, day=29, observance=nearest_workday),
    Holiday('Summer Bank', month=8, day=28, observance=nearest_workday),
    Holiday('Christmas Day', month=12, day=25, observance=nearest_workday),
    Holiday('Boxing Day', month=12, day=26, observance=nearest_workday),
]
UKBankHolidayCal = UKHoliday()
h = UKBankHolidayCal.holidays(datetime(2016, 1, 1), datetime(2016, 12, 31))
for x in h:
    UKdays.append(x.date())

非常感谢任何帮助!

Answer 1

如果你这样做:

import datetime
datetime(2016, 1, 1)

你得到

TypeError: 'module' object is not callable

但如果你这样做

from datetime import datetime
datetime(2016, 1, 1)

有用。

所以问题在于您导入的方式datetime .您必须在您的情况下使用第二个版本，或者您将模块与对象混合在一起，它们具有相同的名称。
