将秒转换为可读格式时间

Question

我有一个包含秒的变量，我想转换为详细的时间格式。我现在就是这样。

runTime = '%s Hours:Minutes:Seconds' % time.strftime("%H:%M:%S", time.gmtime(runTime))

输出：

17:25:46 Hours:Minutes:Seconds 

我希望将其格式化为这样：

 17 Hours 25 Minutes 46 Seconds

最终我希望能够缩短更小的值：

所以如果值是分钟和秒，它会喜欢

15 Minutes 5 Seconds

如果超过 24 小时，那么几天

  1 Days 15 Hours 5 Minutes 1 Seconds

Answer 1

你应该使用优秀的

dateutil

包然后你的任务就变得微不足道了：

>>> from dateutil.relativedelta import relativedelta as rd
>>> fmt = '{0.days} days {0.hours} hours {0.minutes} minutes {0.seconds} seconds'
>>> print(fmt.format(rd(seconds=62745)))
0 days 17 hours 25 minutes 45 seconds

一个高级示例，仅显示那些非零字段的值：

>>> intervals = ['days','hours','minutes','seconds']
>>> x = rd(seconds=12345)
>>> print(' '.join('{} {}'.format(getattr(x,k),k) for k in intervals if getattr(x,k)))
3 hours 25 minutes 45 seconds
>>> x = rd(seconds=1234432)
>>> print(' '.join('{} {}'.format(getattr(x,k),k) for k in intervals if getattr(x,k)))
14 days 6 hours 53 minutes 52 seconds

Answer 2

您应该逐步执行此操作，首先确定天/小时，然后添加分钟/秒。

import time

current_time = time.gmtime()   # Or whatever time.
hours = int(time.strftime("%H", current_time))
days = hours / 24
hours = hours % 24

time_string = ""
if days > 0:
  time_string += "%d Days " % days
if hours > 0:
  time_string += "%d Hours " % hours

time_string += time.strftime("%M Minutes %S Seconds", current_time)

您可以将额外的单词直接放入

time.strftime

的第一个参数中。

%H:%M:%S

不是必需的格式；它更像是字符串格式，您可以在任意位置添加单词，并使参数出现在您想要的位置。

Answer 3

这就是我所拥有的。它是通用的，报告的持续时间从微秒到数年不等，仅根据最重要的信息组成结果。您可以使用

parts_count

来减少或增加返回的时间部分数量。

def readable_duration(seconds: float, parts_count: int = 2) -> str:
    """Returns readable time span out of number of seconds. No rounding."""

    parts_with_units = [
        (60 * 60 * 24 * 365, "y"),
        (60 * 60 * 24 * 7, "w"),
        (60 * 60 * 24, "d"),
        (60 * 60, "h"),
        (60, "m"),
        (1, "s"),
        (1e-3, "ms"),
        (1e-6, "us"),
    ]
    info = ""
    remaining = abs(seconds)
    for time_part, unit in parts_with_units:
        partial_amount = int(remaining // time_part)
        if partial_amount:
            optional_space = " " if info else ""
            info += f"{optional_space}{partial_amount}{unit}"
            remaining %= time_part
            parts_count -= 1
        if not parts_count:
            break
    if not info and seconds != 0:
        return "~0s"
    return info or "0s"


def test_readable_duration():
    assert readable_duration(0) == "0s"
    assert readable_duration(0.0) == "0s"
    assert readable_duration(0.00001234567) == "12us"
    assert readable_duration(1.2345) == "1s 234ms"
    assert readable_duration(12) == "12s"
    assert readable_duration(12.345) == "12s 345ms"
    assert readable_duration(123) == "2m 3s"
    assert readable_duration(1234) == "20m 34s"
    assert readable_duration(12345) == "3h 25m"
    assert readable_duration(123456) == "1d 10h"
    assert readable_duration(1234567) == "2w 6h"
    assert readable_duration(12345678) == "20w 2d"
    assert readable_duration(123456789) == "3y 47w"
    assert readable_duration(1e-10) == "~0s"
