我正在数据库中存储一个datetime 字符串。现在我面临一个问题。当我从数据库中获取字符串时，我需要将其转换回 datetime 对象...

有什么简单的方法可以做到这一点吗？

日期时间字符串如下所示：

2010-11-13 10:33:54.227806

I am storing a datetime string in a database. Now I face a problem. When I fetch the string from the database, I need to convert it back to a datetime object...

Any easy way to do that?

The string of datetime looks like:

2010-11-13 10:33:54.227806

您需要 datetime.strptime(date_string, format)。

from datetime import datetime
datetime.strptime("2010-11-13 10:33:54.227806", "%Y-%m-%d %H:%M:%S.%f")

有关格式字符串的详细信息，请参阅 http://docs.python .org/library/datetime.html#strftime-and-strptime-behavior

You want datetime.strptime(date_string, format).

from datetime import datetime
datetime.strptime("2010-11-13 10:33:54.227806", "%Y-%m-%d %H:%M:%S.%f")

For details on the format string, see http://docs.python.org/library/datetime.html#strftime-and-strptime-behavior

我建议你使用 pip install python-dateutil 安装 python-dateutil

from dateutil import parser
d = parser.parse(yourstring)

：库以“智能”方式从日期字符串中获取 datetime 对象...

I sugggest you install python-dateutil with pip install python-dateutil:

from dateutil import parser
d = parser.parse(yourstring)

This library gets a datetime object from your date string in a 'smart' way...

    time_tuple = (2008, 11, 12, 13, 51, 18, 2, 317, 0)
