將timedelta舍入到最接近的15分鐘

Question

我有一個timedelta，我想舍入到最近的15分鐘。例如，8小時40分鐘將輪到8小時45分鐘，8小時50分鐘將輪到8小時45分鐘。

什麼是最好的方法來實現這一目標？

Answer 1

我結束了創建我自己的解決方案，我沒有發現用於IPython的另一種方式

def round_timedelta(td, period): 
    """ 
    Rounds the given timedelta by the given timedelta period 
    :param td: `timedelta` to round 
    :param period: `timedelta` period to round by. 
    """ 
    period_seconds = period.total_seconds() 
    half_period_seconds = period_seconds/2 
    remainder = td.total_seconds() % period_seconds 
    if remainder >= half_period_seconds: 
     return timedelta(seconds=td.total_seconds() + (period_seconds - remainder)) 
    else: 
     return timedelta(seconds=td.total_seconds() - remainder)

In [4]: print round_timedelta(timedelta(hours=1, minutes=27), timedelta(minutes=15)) 
1:30:00 

In [5]: print round_timedelta(timedelta(hours=1, minutes=30), timedelta(minutes=15)) 
1:30:00 

In [6]: print round_timedelta(timedelta(hours=1, minutes=31), timedelta(minutes=15)) 
1:30:00 

In [7]: print round_timedelta(timedelta(hours=1, minutes=37), timedelta(minutes=15)) 
1:30:00 

In [8]: print round_timedelta(timedelta(hours=1, minutes=38), timedelta(minutes=15)) 
1:45:00
