I feel I'm lacking some link here: why do you think we should do that?
neal at janus ~/build/python/svn/clean-ish $ LC_ALL=de_DE ./python
import locale locale.setlocale(locale.LCALL) 'C' locale.setlocale(locale.LCALL, 'deDE') 'de_DE'
I would have expected the first call to setlocale() to return de_DE. /f solution of adding a flag to the test runner should work for the bug report I mentioned. Part of the reason why I asked was because I'm confused by the current behaviour. Is the first call to setlocale() supposed to return C? If so, always? I was looking for some way for the initial call to setlocale() to return de_DE or whatever other locale I set.
What does "start with the correct locale" mean? What is the "correct locale"? Python should work in any locale,
Hopefully my explanation above answered all those questions.
and locale.format should always give the locale-specific formatting, whereas "%f" % value should always give the result from the "C" locale (regardless of whether the application has called setlocale or not).
Right. I'm working on a patch for this problem which is independent of what I was asking. I really should have started a new thread, but I wasn't completely sure when I asked if there was a relationship. Also, in Georg's snippet, he didn't show that he was setting the locale, only what it was set to.
