java - 法语的本地化持续时间格式

Question

Time4J's code example 的 Python 模拟是什么？ :

// duration in seconds normalized to hours, minutes and seconds
Duration<?> dur = Duration.of(337540, ClockUnit.SECONDS).with(Duration.STD_CLOCK_PERIOD);

// custom duration format => hh:mm:ss
String s1 = Duration.Formatter.ofPattern("hh:mm:ss").format(dur);
System.out.println(s1); // output: 93:45:40

// localized duration format for french
String s2 = PrettyTime.of(Locale.FRANCE).print(dur, TextWidth.WIDE);
System.out.println(s2); // output: 93 heures, 45 minutes et 40 secondes

很容易得到93:45:40:

#!/usr/bin/env python3
from datetime import timedelta

dur = timedelta(seconds=337540)
print(dur) # -> 3 days, 21:45:40
fields = {}
fields['hours'], seconds = divmod(dur // timedelta(seconds=1), 3600)
fields['minutes'], fields['seconds'] = divmod(seconds, 60)
print("%(hours)02d:%(minutes)02d:%(seconds)02d" % fields) # -> 93:45:40

但是我如何在 Python 中模拟 PrettyTime.of(Locale.FRANCE).print(dur, TextWidth.WIDE) Java 代码(不对单元进行硬编码)？

Answer 1

babel module允许接近所需的输出:

from babel.dates import format_timedelta # $ pip install babel

print(", ".join(format_timedelta(timedelta(**{unit: fields[unit]}),
                                 granularity=unit.rstrip('s'),
                                 threshold=fields[unit] + 1,
                                 locale='fr')
                for unit in "hours minutes seconds".split()))
# -> 93 heures, 45 minutes, 40 secondes

它自动处理语言环境和复数形式，例如，对于 dur = timedelta(seconds=1)，它产生:

0 heure, 0 minute, 1 seconde

也许更好的解决方案是使用gettext 等标准工具手动翻译格式字符串。
