Name `localization` is chosen to avoid overlap with builtin `locale` module. )contextmanagerN)optionslc_varc csZt}z>t||t}tdd|Dr>d|Vn|VW5t||XdS)aE Context manager for temporarily setting a locale. Parameters ---------- new_locale : str or tuple A string of the form .. For example to set the current locale to US English with a UTF8 encoding, you would pass "en_US.UTF-8". lc_var : int, default `locale.LC_ALL` The category of the locale being set. Notes ----- This is useful when you want to run a particular block of code under a particular locale, without globally setting the locale. This probably isn't thread-safe. css|]}|dk VqdSN).0xrr?/tmp/pip-unpacked-wheel-tiezk1ph/pandas/_config/localization.py 'szset_locale...N)locale getlocale setlocalealljoin)Z new_localerZcurrent_localeZnormalized_localerrr set_locales  r)lcrreturnc CsBzt||dW5QRXWnttjfk r8YdSXdSdS)aj Check to see if we can set a locale, and subsequently get the locale, without raising an Exception.

If ``True``, only locales that can be set without throwing an ``Exception`` are returned. locale_getter : callable The function to use to retrieve the current locales. This should return a string with each locale separated by a newline character. Returns ------- locales : list of strings A list of locale strings that can be set with ``locale.setlocale()``.
