Question

如何從日期對象python獲取日期時間？

我想

import datetime as dt

today = dt.date.today()
date_time = dt.datetime(today.year, today.month, today.day)

更容易解決方案？

Answer 1

有幾種方法可以做到這一點：

mydatetime = datetime.datetime(d.year, d.month, d.day)

要么

mydatetime = datetime.combine(d, datetime.time())

要么

mydatetime = datetime.datetime.fromordinal(d.toordinal())

我認為第一種是最常用的。

Answer 2

嘗試這個：

import datetime

print 'Now    :', datetime.datetime.now()
print 'Today  :', datetime.datetime.today()
print 'UTC Now:', datetime.datetime.utcnow()

d = datetime.datetime.now()
for attr in [ 'year', 'month', 'day', 'hour', 'minute', 'second', 'microsecond']:
   print attr, ':', getattr(d, attr)

要么

mdt = datetime.datetime(d.year, d.month, d.day) #generalized
