如何从日期时间获取日期 [英] how to get the date from datetime

问题描述

我有一个datetime对象，我想分别获取一个带日期的字符串和一个带时间的字符串。我希望theDate和theTime的值是字符串。

I have a datetime object and I'm trying to individually get a string with the date, and one with the time. I'd like the values for theDate and theTime to be strings.

theDate = myDatetime.date()
theTime = myDatetime.time()

类似这些内容。我尝试了str（datetime.date），但是它给了我一个内存中的参考，还有其他想法吗？预先感谢您的帮助。

Something along those lines. I tried str(datetime.date) but it gave me a reference in memory, any other ideas? Thanks in advance for any help.

推荐答案

使用 datetime.strftime（）方法上的datetime对象：

Use the datetime.strftime() method on the datetime object:

theDate = myDatetime.strftime('%Y-%m-%d')
theTime = myDatetime.strftime('%H:%M:%S')

或者，将您的日期设为和 time 对象转换为字符串作为其默认字符串表示形式：

Alternatively, turn your date and time objects into strings for their default string representations:

theDate = str(myDatetime.date())
theTime = str(myDatetime.time())

Demo：

>>> import datetime
>>> myDatetime = datetime.datetime.now()
>>> myDatetime.strftime('%Y-%m-%d')
'2013-06-19'
>>> myDatetime.strftime('%H:%M:%S')
'16:49:44'
>>> str(myDatetime.date())
'2013-06-19'
>>> str(myDatetime.time())
'16:49:44.447010'

默认 datetime.time 对象的字符串格式包括微秒部分。

The default string format for datetime.time objects includes the microsecond component.
