[英]python - locale in dateutil / parser
I set我设置
locale.setlocale(locale.LC_TIME, ('de', 'UTF-8'))
the string to parse is:要解析的字符串是:

I use:我用:
note_date = parser.parse(result.group(2))
but get the following error:但得到以下错误:

a debug show that parser is not using the "correct" dateutil values (german), it's still using the english ones.调试显示解析器没有使用“正确的” dateutil 值(德语),它仍在使用英语值。
I'm sure I'm missing something obvious here, but can't find it.我确定我在这里遗漏了一些明显的东西,但找不到。
Thanks.谢谢。
dateutil.parser
doesn't use locale
. dateutil.parser
不使用locale
。 You'll need to subclass dateutil.parser.parserinfo
and construct a German equivalent:.您需要将
dateutil.parser.parserinfo
子类dateutil.parser.parserinfo
并构造一个德语等效项:。
from dateutil import parser
class GermanParserInfo(parser.parserinfo):
WEEKDAYS = [("Mo.", "Montag"),
("Di.", "Dienstag"),
("Mi.", "Mittwoch"),
("Do.", "Donnerstag"),
("Fr.", "Freitag"),
("Sa.", "Samstag"),
("So.", "Sonntag")]
s = 'Montag, 11. April 2016 19:35:57'
note_date = parser.parse(s, parserinfo=GermanParserInfo())
You'd need to extend this to also work for other values, such as month names.您需要将其扩展为也适用于其他值,例如月份名称。
In another answer, I answered a simple Locale aware parseinfo class .在另一个答案中,我回答了一个简单的Locale 感知 parseinfo class 。 This isn't a complete solution for all languages in the world, but solved all my localization problems.
这不是世界上所有语言的完整解决方案,但解决了我所有的本地化问题。
Here it is:这是:
import calendar
from dateutil import parser
class LocaleParserInfo(parser.parserinfo):
WEEKDAYS = zip(calendar.day_abbr, calendar.day_name)
MONTHS = list(zip(calendar.month_abbr, calendar.month_name))[1:]
And you can use:你可以使用:
In [1]: import locale;locale.setlocale(locale.LC_ALL, "pt_BR.utf8")
In [2]: from localeparserinfo import LocaleParserInfo
In [3]: from dateutil.parser import parse
In [4]: parse("Ter, 01 Out 2013 14:26:00 -0300", parserinfo=PtParserInfo())
Out[4]: datetime.datetime(2013, 10, 1, 14, 26, tzinfo=tzoffset(None, -10800))
Test it and take a look the class variables in the original parseinfo, specially the HMS variable.测试一下,看看原始解析信息中的类变量,特别是HMS变量。 Maybe'll need to declare other variables.
也许需要声明其他变量。
The way to implement multiple languages at once.一次实现多种语言的方法。 I know there are other possibilites with
calendar.day_abbr, calendar.day_name
but this was the most convinient one for me.我知道
calendar.day_abbr, calendar.day_name
还有其他可能,但这对我来说是最方便的。 Just combine all the month names and list them down all togehter.只需结合所有月份名称并将它们全部列出。 These then will get accepted by the
dateutil.parser
然后这些将被
dateutil.parser
接受
from dateutil import parser as dateparser
class LocaleParserInfo(dateparser.parserinfo):
MONTHS = [('Jan', 'Januar', 'January', 'Jänner'),
('Feb', 'Februar', 'February'),
('Mrz', 'März', 'March', 'Mar'),
('Apr', 'April'),
('Mai', 'May'),
('Jun', 'Juni', 'June'),
('Jul', 'Juli', 'July'),
('Aug', 'August'),
('Sep', 'September'),
('Okt', 'Oktober', 'October', 'Oct'),
('Nov', 'November'),
('Dez', 'Dezember', 'Dec', 'December')]
parsed_date = dateparser.parse("31 Jänner 2022", dayfirst=True, parserinfo=LocaleParserInfo())
parsed_date = dateparser.parse("31.December 2022", dayfirst=True, parserinfo=LocaleParserInfo())
