如果您希望将日期上的“从午夜开始的秒数”的单个值转换为datetime对象或具有HH:MM:SS的字符串，那么上面的解决方案将起作用，但我选择这个页面是因为我想在pandas的整个dataframe列上执行此操作。如果有人想知道如何在同一时间为多个值做到这一点，最后为我工作的是:

 mydate='2015-03-01'
 df['datetime'] = datetime.datetime(mydate) + \ 
                  pandas.to_timedelta(df['seconds_since_midnight'], 's')

使用日期时间:

使用':0>8'格式:

from datetime import timedelta

"{:0>8}".format(str(timedelta(seconds=66)))
# Result: '00:01:06'

"{:0>8}".format(str(timedelta(seconds=666777)))
# Result: '7 days, 17:12:57'

"{:0>8}".format(str(timedelta(seconds=60*60*49+109)))
# Result: '2 days, 1:01:49'

没有':0>8'格式:

"{}".format(str(timedelta(seconds=66)))
# Result: '00:01:06'

"{}".format(str(timedelta(seconds=666777)))
# Result: '7 days, 17:12:57'

"{}".format(str(timedelta(seconds=60*60*49+109)))
# Result: '2 days, 1:01:49'

使用时间:

from time import gmtime
from time import strftime

# NOTE: The following resets if it goes over 23:59:59!

strftime("%H:%M:%S", gmtime(125))
# Result: '00:02:05'

strftime("%H:%M:%S", gmtime(60*60*24-1))
# Result: '23:59:59'

strftime("%H:%M:%S", gmtime(60*60*24))
# Result: '00:00:00'

strftime("%H:%M:%S", gmtime(666777))
# Result: '17:12:57'
# Wrong

我是这样得到它的。

def sec2time(sec, n_msec=3):
    ''' Convert seconds to 'D days, HH:MM:SS.FFF' '''
    if hasattr(sec,'__len__'):
        return [sec2time(s) for s in sec]
    m, s = divmod(sec, 60)
    h, m = divmod(m, 60)
    d, h = divmod(h, 24)
    if n_msec > 0:
        pattern = '%%02d:%%02d:%%0%d.%df' % (n_msec+3, n_msec)
    else:
        pattern = r'%02d:%02d:%02d'
    if d == 0:
        return pattern % (h, m, s)
    return ('%d days, ' + pattern) % (d, h, m, s)

一些例子:

$ sec2time(10, 3)
Out: '00:00:10.000'

$ sec2time(1234567.8910, 0)
Out: '14 days, 06:56:07'

$ sec2time(1234567.8910, 4)
Out: '14 days, 06:56:07.8910'

$ sec2time([12, 345678.9], 3)
Out: ['00:00:12.000', '4 days, 00:01:18.900']

通过使用divmod()函数，它只做一个除法就能得到商和余数，你只需要两个数学运算就能很快得到结果:

m, s = divmod(seconds, 60)
h, m = divmod(m, 60)

然后使用字符串格式将结果转换为您想要的输出:

print('{:d}:{:02d}:{:02d}'.format(h, m, s)) # Python 3
print(f'{h:d}:{m:02d}:{s:02d}') # Python 3.6+

你可以使用datetime。timedelta功能:

>>> import datetime
>>> str(datetime.timedelta(seconds=666))
'0:11:06'

division = 3623 // 3600 #to hours
division2 = 600 // 60 #to minutes
print (division) #write hours
print (division2) #write minutes
