Question

如何在python中添加一个秒数组到引用日期时间，例如：

ref_time = datetime.datetime(year=2017, month=6, day=5, hour=10, minute=30, second=30)

secs = (0,1,2,3,4,5,6,7,8,9,10)

结果必须是：

2017,6,5,10,30,30

2017,6,5,10,30,31

2017,6,5,10,30,32

2017,6,5,10,30,33 等等

我试过这个，但它不起作用，我做错了什么？

d = datetime.timedelta(seconds=np.int(secs))
new_timestamp = timestamp+d

对不起这个简单的问题，我对python

很新

timedelta接受一个参数作为第二个参数，这意味着您需要一次传递secs元组中的秒数。您只需使用列表解析即可实现此目的：

In [1]: import datetime

In [2]: ref_time = datetime.datetime(year=2017, month=6, day=5, hour=10, minute=30, second=30)

In [3]: secs = (0,1,2,3,4,5,6,7,8,9,10)

In [4]: [ref_time + datetime.timedelta(seconds=i) for i in secs]
Out[4]: 
[datetime.datetime(2017, 6, 5, 10, 30, 30),
 datetime.datetime(2017, 6, 5, 10, 30, 31),
 datetime.datetime(2017, 6, 5, 10, 30, 32),
 datetime.datetime(2017, 6, 5, 10, 30, 33),
 datetime.datetime(2017, 6, 5, 10, 30, 34),
 datetime.datetime(2017, 6, 5, 10, 30, 35),
 datetime.datetime(2017, 6, 5, 10, 30, 36),
 datetime.datetime(2017, 6, 5, 10, 30, 37),
 datetime.datetime(2017, 6, 5, 10, 30, 38),
 datetime.datetime(2017, 6, 5, 10, 30, 39),
 datetime.datetime(2017, 6, 5, 10, 30, 40)]

向参考日期时间添加秒数组
