问题描述
我正在用Python编写程序，我需要根据用户的语言环境输出日期:
I was programming a program in Python, where I need to output date as per user's locale:
- 获取按用户输入指定的国家/地区的时区列表(是否使用pytz)
- 获取用户的语言环境(我不知道该怎么做)
是否有从县/时区获取语言环境的方法，或者需要遵循其他方法?
Is there a way to get locale from county/timezone or some other method needs to be followed?
还是我需要从用户本身获取区域设置输入?
Or do I need to get the locale input from user itself?
编辑
该程序应为网络应用程序.用户可以向我提供他的国家.但是他是否还必须明确向我提供语言环境，还是可以从他的时区/国家/地区获取它?
The program is to be a web-app. The user can provide me his country. But does he have to explicitly provide me the locale also or can I get it from his timezone/country?
推荐答案
我认为不可能将国家/时区转换为单个正确"的语言环境...在使用多种语言的国家/地区中，没有1:语言和时区之间有1种关系.
I don't think it's possible to convert country + timezone into a single 'correct' locale... in countries with multiple languages there is not a 1:1 relation between language and timezone.
我能看到的最接近的是使用 Babel :
The closest I can see is to use Babel:
from babel import Locale
Locale.parse('und_BR') # 'und' here means unknown
>>> Locale('pt', territory='BR')
这为您提供了该国家/地区的一个最可能"(或默认)语言环境.为了正确处理语言，您需要向用户询问其首选语言.
This gives you a single 'most likely' (or default) locale for the country. To handle the languages properly you need to ask the user their preferred language.
这篇关于有没有办法从国家或时区获取语言环境?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
