That's fine. If you only pass in the category it's just a query.
locale.getlocale defaults to a single category (LC_CTYPE) because of
the parsing it does to create the tuple. The issue is that an LC_ALL
query returns all of the categories, delimited by semicolons, if
they're not all the same. In this case locale.getlocale(LC_ALL) raises
a TypeError. But there's no problem using such a locale string with
Also, on Windows locale.getdefaultlocale uses win32 GetLocaleInfo, set
to return ISO 639/3166 language/country codes. These codes don't work
with the MS CRT setlocale, so locale.resetlocale fails.
setlocale(LC_ALL, '') is supported to reset to the default. More here:
