概况Link to this heading#

\n

The goal of internationalization and localization is to allow a single Web\napplication to offer its content in languages and formats tailored to the\naudience.

\n

Django has full support for translation of text, formatting of dates, times and numbers, and time zones.

\n

Essentially, Django does two things:

\n\n

Obviously, translation depends on the target language, and formatting usually\ndepends on the target country. This information is provided by browsers in\nthe Accept-Language header. However, the time zone isn't readily available.

\n
\n
locale nameLink to this term#

A locale name, either a language specification of the form ll or a\ncombined language and country specification of the form ll_CC.\nExamples: it, de_AT, es, pt_BR. The language part is\nalways in lower case and the country part in upper case. The separator\nis an underscore.

\n
\n
language codeLink to this term#

Language codes\nare generally represented in lower-case, but the HTTP Accept-Language\nheader is case-insensitive. The separator is a dash.

\n
\n
message fileLink to this term#

A message file is a plain-text file, representing a single language,\nthat contains all available translation strings and how they should be represented in the given\nlanguage. Message files have a .po file extension.

\n
