Datetime and Pytz Timezone .weekday() issue

Question

当我尝试创建特定订单 createdAt数据数据的直方图时，我会遇到问题。问题在于，即使创建了时区感知数据量，.weekday()也显示为同一天，即使它应该是不同的时间

我用来测试此事件的代码如下：

import datetime
import pytz
value = {
    'createdAt': '2017-04-24T00:48:03+00:00'
}
created_at = datetime.datetime.strptime(value['createdAt'], '%Y-%m-%dT%H:%M:%S+00:00')
timezone = pytz.timezone('America/Los_Angeles')
created_at_naive = created_at
created_at_aware = timezone.localize(created_at_naive)
print(created_at_naive) # 2017-04-24 00:48:03
print(created_at_aware) # 2017-04-24 00:48:03-07:00
print(created_at_naive.weekday()) # 0 (Monday)
print(created_at_aware.weekday()) # 0 (should be Sunday)

Answer 1

问题是您需要实际将日期时间更改为新时区：

>>> timezone('UTC').localize(created_at)
datetime.datetime(2017, 4, 24, 0, 48, 3, tzinfo=<UTC>)
>>>timezone('UTC').localize(created_at).astimezone(timezone('America/Los_Angeles'))
datetime.datetime(2017, 4, 23, 17, 48, 3, tzinfo=<DstTzInfo 'America/Los_Angeles' PDT-1 day, 17:00:00 DST>)
