如果你需要约会时间。时间值，你可以用这个技巧:

my_time = (datetime(1970,1,1) + timedelta(seconds=my_seconds)).time()

您不能将timedelta添加到time，但可以将它添加到datetime。

UPD:这是同一技巧的另一种变体:

my_time = (datetime.fromordinal(1) + timedelta(seconds=my_seconds)).time()

你可以用任何大于0的数字来代替1。这里我们使用的事实是datetime.fromordinal将总是返回时间分量为零的datetime对象。

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

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+

有点离题，但可能对某人有用

def time_format(seconds: int) -> str:
    if seconds is not None:
        seconds = int(seconds)
        d = seconds // (3600 * 24)
        h = seconds // 3600 % 24
        m = seconds % 3600 // 60
        s = seconds % 3600 % 60
        if d > 0:
            return '{:02d}D {:02d}H {:02d}m {:02d}s'.format(d, h, m, s)
        elif h > 0:
            return '{:02d}H {:02d}m {:02d}s'.format(h, m, s)
        elif m > 0:
            return '{:02d}m {:02d}s'.format(m, s)
        elif s > 0:
            return '{:02d}s'.format(s)
    return '-'

结果:

print(time_format(25*60*60 + 125)) 
>>> 01D 01H 02m 05s
print(time_format(17*60*60 + 35)) 
>>> 17H 00m 35s
print(time_format(3500)) 
>>> 58m 20s
print(time_format(21)) 
>>> 21s

下面是一个简单的程序，它读取当前时间并将其转换为以小时、分钟和秒为单位的一天时间

import time as tm #import package time
timenow = tm.ctime() #fetch local time in string format

timeinhrs = timenow[11:19]

t=tm.time()#time.time() gives out time in seconds since epoch.

print("Time in HH:MM:SS format is: ",timeinhrs,"\nTime since epoch is : ",t/(3600*24),"days")

输出为

Time in HH:MM:SS format is:  13:32:45 
Time since epoch is :  18793.335252338384 days

小时(h)秒除以3600(60分钟/小时* 60秒/分钟)

分钟(m)由剩余秒数(小时计算余数，%)除以60(60秒/分钟)计算得出

同样，秒(s)按小时余数和分钟计算。

剩下的只是字符串格式化!

def hms(seconds):
    h = seconds // 3600
    m = seconds % 3600 // 60
    s = seconds % 3600 % 60
    return '{:02d}:{:02d}:{:02d}'.format(h, m, s)

print(hms(7500))  # Should print 02h05m00s
