发现两天之间的天数差异

Question

我想知道以下日期之间的天差异...任何人都可以提供有关如何实现这一目标的输入？

CR created date 
2013-11-01 
Current date 
2013-11-09 18:17:53.196126 

Answer 1

使用datetime模块。如果你有一个datetime.datetime对象A和datetime.date对象B，所不同的是：

A.date() - B 

试试吧;-)

例子：

>>> from datetime import datetime, date 
>>> A = datetime.strptime("2013-11-09 18:17:53.196126", "%Y-%m-%d %H:%M:%S.%f") 
>>> B = date(*map(int, "2013-11-01".split("-"))) 
>>> print A 
2013-11-09 18:17:53.196126 
>>> print B 
2013-11-01 
>>> print A.date() - B 
8 days, 0:00:00 

Answer 2

首先，你必须改变输入到python知道的类型 - datetime。然后使用内置函数。

>>> from datetime import datetime 
>>> A = datetime.strptime('2013-11-01', '%Y-%m-%d') 
>>> A 
datetime.datetime(2013, 11, 1, 0, 0) 
>>> B = datetime.strptime('2013-11-09 18:17:53.196126', '%Y-%m-%d %H:%M:%S.%f') 
>>> B 
datetime.datetime(2013, 11, 9, 18, 17, 53, 196126) 
>>> diff = B - A 
>>> diff 
datetime.timedelta(8, 65873, 196126) 
>>> diff.total_seconds() 
757073.196126 
>>> diff.total_seconds()/(60 * 60 * 24) 
8.762421251458333
