Convert datetime format into seconds
提问by PythonEnthusiast
My date is in the format DD/MM/YYYY HH:MM:SS, ie 16/08/2013 09:51:43. How can I convert the date into python seconds using total_seconds()or using any other python function?
我的日期是格式DD/MM/YYYY HH:MM:SS，即16/08/2013 09:51:43. 如何使用total_seconds()或使用任何其他 python 函数将日期转换为 python 秒？

Here's how you can do it:
您可以这样做：
>>> from datetime import datetime
>>> import time
>>> s = "16/08/2013 09:51:43"
>>> d = datetime.strptime(s, "%d/%m/%Y %H:%M:%S")
>>> time.mktime(d.timetuple())
1376632303.0

>>> tt = datetime.datetime( 2013, 8, 15, 6, 0, 0 )
>>> print int(tt.strftime('%s'))

Seconds since when?
从什么时候开始几秒？
See this code for general second computation:
有关一般第二次计算，请参阅此代码：
from datetime import datetime
since = datetime( 1970, 8, 15, 6, 0, 0 )
mytime = datetime( 2013, 6, 11, 6, 0, 0 )
diff_seconds = (mytime-since).total_seconds()
UPDATE: if you need unix timestamp (i.e. seconds since 1970-01-01) you can use the language default value for timestamp of 0 (thanks to comment by J.F. Sebastian):
更新：如果您需要 unix 时间戳（即自 1970-01-01 以来的秒数），您可以使用时间戳为 0 的语言默认值（感谢 JF Sebastian 的评论）：
from datetime import datetime
mytime = datetime( 2013, 6, 11, 6, 0, 0 )
diff_seconds = (mytime-datetime.fromtimestamp(0)).total_seconds()
