python——秒（s）的转换

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
#n=0 --> 0d0h0m0s
#n=63 --> 0d0h1m3s
#n=1235 --> 0d0h20m35s
n = int(input('n = '))
if n < 0:
    exit()
S = 1
M = 60 * S
H = 60 * M
D = 24 * H
d = n // D
n = n % D
h = n // H
n = n % H
m = n // M
n = n % M
s = n // S
print('%dd%dh%dm%ds' %(d, h, m, s))

如：
[root@lpc 04-3-通过秒求时间]# python3 04-4.py 
n = 1600
0d0h26m40s
