如何在python 3.x中将秒转换为hh：mm：ss

Question

我只需要数学运算符就可以做到这一点，但是我总是在领域中得到高得离谱的数字。

def main():
seconds = int(input('Seconds to be converted? '))
days = seconds / 86400
seconds = seconds - (days * 86400)
hours = seconds / 3600
seconds = seconds - (hours * 3600)
minutes = seconds / 60
seconds = seconds - (minutes * 60)

print('-------------')
print('You entered: ', seconds)
print('')
print('The converted time is: ', format(days, '1.0f'), ':', format(hours, '1.0f'), ':', format(minutes, '1.0f'), ':', format(seconds, '1.0f'))

Answer 1

>>> s = 12345  # seconds
>>> '{:02}:{:02}:{:02}'.format(s//3600, s%3600//60, s%60)
'03:25:45'

Answer 2

为了获得最大的可重用性，该datetime库将很方便：

例如，此代码：

import datetime
s=12345
x=datetime.timedelta(seconds=s)
print x

输出：

3:25:45
