python-以特定格式获取时间

Question

I need to get time in format: hour:minutes:seconds. But if I use:

 time.strftime('%H:%M:%S', time.gmtime(my_time))) #my_time is float

hour have a 24-hour clock (00 to 23). And when I have for example 25 hour and 2 minutes, it writes 1:02:00, but I need 25:02:00. How can I solve it? Thank you.

Don't use time.strftime() to format elapsed time. You can only format a time of day value with that; the two types of values are related but not the same thing.

You'll need to use custom formatting instead.

If my_time is elapsed time in seconds, you can use the following function to format it to a hours:minutes:seconds format:

def format_elapsed_time(seconds):
    seconds = int(seconds + 0.5)  # round to nearest second
    minutes, seconds = divmod(seconds, 60)
    hours, minutes = divmod(minutes, 60)
    return '{:02d}:{:02d}:{:02d}'.format(hours, minutes, seconds)

Demo:

>>> def format_elapsed_time(seconds):
...     seconds = int(seconds + 0.5)  # round to nearest second
...     minutes, seconds = divmod(seconds, 60)
...     hours, minutes = divmod(minutes, 60)
...     return '{:02d}:{:02d}:{:02d}'.format(hours, minutes, seconds)
... 
>>> format_elapsed_time(90381.33)
'25:06:21'
