如何從日期對象python獲取日期時間？

Question

如何從日期對象python獲取datetime？

我覺得

import datetime as dt 

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

任何簡單的解決方案？

Answer 1

有幾個方法可以做到這一點：

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

或

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

或

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

我認爲首先是最常用的。

Answer 2

試試這個：

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) 

或

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