A `Locale` object can also be instantiated from a raw locale string:

`Locale` objects provide access to a collection of locale data, such as
territory and language names, number and date format patterns, and more:

If a locale is requested for which no locale data is available, an
`UnknownLocaleError` is raised:

>>> l = Locale.parse('de-DE', sep='-')

If the `identifier` parameter is not a string, but actually a `Locale`
object, that object is returned:
>>> Locale.parse(l)
Locale('de', territory='DE')
This also can perform resolving of likely subtags which it does
by default. This is for instance useful to figure out the most
likely locale for a territory you can use ``'und'`` as the
language tag:
>>> Locale.parse('und_AT')
Locale('de', territory='AT')
:param identifier: the locale identifier string
:param sep: optional component separator
:param resolve_likely_subtags: if this is specified then a locale will
have its likely subtag resolved if the
locale otherwise does not exist. For
instance ``zh_TW`` by itself is not a
locale that exists but Babel can
automatically expand it to the full
form of ``zh_hant_TW``. Note that this
expansion is only taking place if no
locale exists otherwise. For instance
there is a locale ``en`` that can exist
by itself.

identifier

By default, some web browsers unfortunately do not include the territory
in the locale identifier for many locales, and some don't even allow the
user to easily add the territory. So while you may prefer using qualified
locale identifiers in your web-application, they would not normally match
the language-only locale sent by such browsers. To workaround that, this
function uses a default mapping of commonly used langauge-only locale
identifiers to identifiers including the territory:
>>> negotiate_locale(['ja', 'en_US'], ['ja_JP', 'en_US'])
'ja_JP'
Some browsers even use an incorrect or outdated language code, such as "no"
for Norwegian, where the correct locale identifier would actually be "nb_NO"
(Bokmål) or "nn_NO" (Nynorsk). The aliases are intended to take care of
such cases, too:
>>> negotiate_locale(['no', 'sv'], ['nb_NO', 'sv_SE'])
'nb_NO'
You can override this default mapping by passing a different `aliases`
dictionary to this function, or you can bypass the behavior althogher by
setting the `aliases` parameter to `None`.

The default component separator is "_", but a different separator can be
specified using the `sep` parameter:
>>> parse_locale('zh-CN', sep='-')
('zh', 'CN', None, None)
If the identifier cannot be parsed into a locale, a `ValueError` exception
is raised:
>>> parse_locale('not_a_LOCALE_String')
Traceback (most recent call last):
...
ValueError: 'not_a_LOCALE_String' is not a valid locale identifier
Encoding information and locale modifiers are removed from the identifier:
>>> parse_locale('it_IT@euro')
('it', 'IT', None, None)
>>> parse_locale('en_US.UTF-8')
('en', 'US', None, None)
>>> parse_locale('de_DE.iso885915@euro')
('de', 'DE', None, None)
