Datetime 如何修复使用boto3在mturk中扩展HIT时出现的日期时间错误

正在尝试延长每个用户的点击列表的过期时间

获取错误：

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-59-e0764e20a54b> in <module>()
      2     response = client.update_expiration_for_hit(
      3         HITId=hit_id,
----> 4         ExpireAt=datetime(2017, 4, 9, 19, 9, 41, tzinfo=tzlocal())
      5     )

NameError: name 'datetime' is not defined

---

没用。建议？

这只是我的Python设置的问题，与boto3无关

import datetime
from dateutil.tz import tzlocal

ExpireAt=(2017, 4, 9, 19, 9, 41, tzinfo=tzlocal())

import datetime
from dateutil.tz import tzlocal
