Question

我有一列花车。我想将它们转换为格式为hh:mm的时间戳。我也希望将它们四舍五入到最近的半小时。

这是转换规则：

1.0表示00:01，我想将它们四舍五入到00:00
735.0表示07:35，我想将它们四舍五入到07:30
2346.0表示23:46，我想将它们四舍五入到00:00

试试这个（没有经过全面测试，但你明白了）：

from datetime import date, timedelta, datetime, time

def roundTime(dt=None, dateDelta=timedelta(minutes=15)):
    """Round a datetime object to a multiple of a timedelta
    dt : datetime.datetime object, default now.
    dateDelta : timedelta object, we round to a multiple of this, default 1 minute.
    Author: Thierry Husson 2012 - Use it as you want but don't blame me.
            Stijn Nevens 2014 - Changed to use only datetime objects as variables
    """
    roundTo = dateDelta.total_seconds()

    if dt == None : dt = datetime.now()
    seconds = (dt - dt.min).seconds
    # // is a floor division, not a comment on following line:
    rounding = (seconds+roundTo/2) // roundTo * roundTo
    return dt + timedelta(0,rounding-seconds,-dt.microsecond)


time_input = 735.0
dt = datetime.strptime(str(int(time_input)).zfill(4), "%H%M")
print(roundTime(dt,timedelta(minutes=15)).strftime('%H:%M'))
