Date Time split in python
提问by Saravana Murthy
I have to split a date time which I get from a software in the below format to separate variables (year,month,day,hour, min,sec)
我必须分割我从以下格式的软件中获得的日期时间以分隔变量（年、月、日、小时、分钟、秒）
19 Nov 2015 18:45:00.000
Note : There is two spaces between the date and time. The whole date and time is stored in a single string variable. Please help me in this regards.
注意：日期和时间之间有两个空格。整个日期和时间存储在单个字符串变量中。请在这方面帮助我。
Thanks in advance.
提前致谢。

Below solution should work for you:
以下解决方案应该适合您：
import datetime
string = "19 Nov 2015 18:45:00.000"
date = datetime.datetime.strptime(string, "%d %b %Y %H:%M:%S.%f")
print date
Output would be:
输出将是：
2015-11-19 18:45:00
And you can access the desired values with:
您可以通过以下方式访问所需的值：
>>> date.year
2015
>>> date.month
11
>>> date.day
19
>>> date.hour
18
>>> date.minute
45
>>> date.second
0
You can check datetime's package documentationunder section 8.1.7 for srtptimefunction's usage.

Use datetime.strptime(your_string, format)
用 datetime.strptime(your_string, format)
To contsruct the formatstring, consult the documentation: https://docs.python.org/2/library/datetime.html#strftime-and-strptime-behavior
要构造format字符串，请参阅文档：https: //docs.python.org/2/library/datetime.html#strftime-and-strptime-behavior
From there, you can easily get the year, month, etc.(also in the documentation)
从那里，您可以轻松获取年、月等（也在文档中）

首先pip install python-dateutil然后做：
>>> from dateutil.parser import parse

As an alternative to wim's answer, if you don't want to install a package, you can do it like so:
作为 wim 的答案的替代方法，如果您不想安装软件包，可以这样做：
import datetime
s = "19 Nov 2015 18:45:00.000"
d = datetime.datetime.strptime(s, "%d %b %Y %H:%M:%S.%f")
print d.year
print d.month
print d.day
print d.hour
print d.minute
print d.second
This outputs:
这输出：
2015
11
19
18
45
0
This utilizes strptimeto parse the string.
这strptime用于解析字符串。
