Python calculating time difference, to give ‘years, months, days, hours, minutes and seconds’ in 1
提问by Mark K
I want to know how many years, months, days, hours, minutes and seconds in between '2014-05-06 12:00:56' and '2012-03-06 16:08:22'. The result shall looked like: “the difference is xxx year xxx month xxx days xxx hours xxx minutes”
我想知道“2014-05-06 12:00:56”和“2012-03-06 16:08:22”之间有多少年、月、日、小时、分钟和秒。结果应如下所示：“差异为 xxx 年 xxx 月 xxx 天 xxx 小时 xxx 分钟”
For example:
例如：
import datetime
a = '2014-05-06 12:00:56'
b = '2013-03-06 16:08:22'
start = datetime.datetime.strptime(a, '%Y-%m-%d %H:%M:%S')
ends = datetime.datetime.strptime(b, '%Y-%m-%d %H:%M:%S')
diff = start – ends
if I do:
如果我做：
diff.days
It gives the difference in days.
它给出了天数的差异。
What else I can do? And how can I achieve the wanted result?
我还能做什么？我怎样才能达到想要的结果？

Use a relativedeltafrom the dateutil package. This will take into account leap years and other quirks.
使用relativedelta从dateutil包。这将考虑闰年和其他怪癖。
import datetime
from dateutil.relativedelta import relativedelta
a = '2014-05-06 12:00:56'
b = '2013-03-06 16:08:22'
start = datetime.datetime.strptime(a, '%Y-%m-%d %H:%M:%S')
ends = datetime.datetime.strptime(b, '%Y-%m-%d %H:%M:%S')
diff = relativedelta(start, ends)
>>> print "The difference is %d year %d month %d days %d hours %d minutes" % (diff.years, diff.months, diff.days, diff.hours, diff.minutes)
The difference is 1 year 1 month 29 days 19 hours 52 minutes
You might want to add some logic to print for e.g. "2 years" instead of "2 year".
您可能想要添加一些逻辑来打印例如“2 年”而不是“2 年”。

diff is a timedeltainstance.
diff 是一个timedelta实例。
for python2, see: https://docs.python.org/2/library/datetime.html#timedelta-objects
对于 python2，请参见：https: //docs.python.org/2/library/datetime.html#timedelta-objects
for python 3, see: https://docs.python.org/3/library/datetime.html#timedelta-objects
对于 python 3，请参见：https: //docs.python.org/3/library/datetime.html#timedelta-objects
from docs:
来自文档：
timdelta instance attributes (read-only):
timdelta 实例属性（只读）：
- days
- seconds
- microseconds
- 天
- 秒
- 微秒
timdelta instance methods:
timdelta 实例方法：
- total_seconds()
- total_seconds()
timdelta class attributes are:
timdelta 类属性是：
- min
- max
- resolution
- 分钟
- 最大限度
- 解析度
You can use the daysand secondsinstance attributes to calculate what you need.
您可以使用days和seconds实例属性来计算您需要的内容。
for example:
例如：
import datetime
a = '2014-05-06 12:00:56'
b = '2013-03-06 16:08:22'
start = datetime.datetime.strptime(a, '%Y-%m-%d %H:%M:%S')
ends = datetime.datetime.strptime(b, '%Y-%m-%d %H:%M:%S')
diff = start - ends
hours = int(diff.seconds // (60 * 60))
mins = int((diff.seconds // 60) % 60)
