Parameters ---------- new_locale : str or tuple A string of the form <language_country>.<encoding>. 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. c s s | ]}|d k V qd S )N� )�.0�xr r �Q/home/digitalm-up/venv/lib/python3.7/site-packages/pandas/_config/localization.py� <genexpr>' s z set_locale.<locals>.<genexpr>�.N)�locale� getlocale� setlocale�all�join)Z new_localer Zcurrent_localeZnormalized_localer r r � set_locale s r )�lcr �returnc C s@ y t | |d�� W dQ R X W n ttjfk r6 dS X dS dS )aj Check to see if we can set a locale, and subsequently get the locale, without raising an Exception.

Parameters ---------- prefix : str If not ``None`` then return only those locales with the prefix provided. For example to get all English language locales (those that start with ``"en"``), pass ``prefix="en"``. normalize : bool Call ``locale.normalize`` on the resulting list of available locales. 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()``. For example:: locale.setlocale(locale.LC_ALL, locale_string) On error will return None (no locale available, e.g. Windows) N� )�encodingz windows-1252z.*� )r �CalledProcessError�split�append�strr �displayr � UnicodeError� TypeErrorr �re�compile�findallr )�prefixr Z locale_getterZ raw_localesZ out_localesr �pattern�foundr r r � get_localesi s& r/ )�__doc__� contextlibr r r) r Zpandas._config.configr �LC_ALL�intr r% �boolr r r r/ r r r r �<module> s
