如何在Python中格式化从秒到小时,分钟,秒和毫秒的经过时间？

Question

如何格式化从秒到小时,分钟,秒的时间？

我的代码:

start = time.time()
... do something
elapsed = (time.time() - start)

实际产量:

0.232999801636

期望/预期输出:

00:00:00.23 

Answer 1

你可以利用timedelta:

>>> from datetime import timedelta
>>> str(timedelta(seconds=elapsed))
'0:00:00.233000'

Answer 2

如果您想要包括0.232999801636输入中的时间:

import time
start = time.time()
end = time.time()
hours, rem = divmod(end-start, 3600)
minutes, seconds = divmod(rem, 60)
print("{:0>2}:{:0>2}:{:05.2f}".format(int(hours),int(minutes),seconds))

例:

In [12]: def timer(start,end):
   ....:         hours, rem = divmod(end-start, 3600)
   ....:         minutes, seconds = divmod(rem, 60)
   ....:         print("{:0>2}:{:0>2}:{:05.2f}".format(int(hours),int(minutes),seconds))
   ....:     

In [13]: timer(12345.242,12356.434)
00:00:11.19
In [14]: timer(12300.242,12600.5452)
00:05:00.30
In [19]: timer(0.343,86500.8743)
24:01:40.53
In [16]: timer(0.343,865000.8743)
 240:16:40.53    
In [17]: timer(0,0.232999801636)
00:00:00.23

Answer 3

strftime其本身的功能可以time在有限制的情况下使用（滥用）（无毫秒且<24小时）

elapsed = 4*3600 + 13*60 + 6                        # 15186 s
time.strftime("%Hh%Mm%Ss", time.gmtime(elapsed))   # '04h13m06s'
