The example in the doc shows```python>>> import locale>>> loc = locale.getlocale()  # get current locale# use German locale; name might vary with platform>>> locale.setlocale(locale.LC_ALL, 'de_DE')>>> locale.strcoll('f\xe4n', 'foo')  # compare a string containing an umlaut>>> locale.setlocale(locale.LC_ALL, '')   # use user's preferred locale>>> locale.setlocale(locale.LC_ALL, 'C')  # use default (C) locale>>> locale.setlocale(locale.LC_ALL, loc)  # restore saved locale```However locale.getlocale() does not return the locale for all categories (locale.LC_ALL is even not allowed) but the locale for the LC_CTYPE category.Therefore restoring it using `locale.setlocale(locale.LC_ALL, loc)` does not actually restore the initial settings, and may even fail on some platforms (on mine it does).The correct example should have the first line of code replaced with```>>> loc = locale.setlocale(locale.LC_ALL)  # get current locale```Note: this issue was first reported in the `pandas` library athttps://github.com/pandas-dev/pandas/issues/46595
