>>> import time
>>> time.strftime("%c")
'Sat Dec 14 00:26:57 2013'
>>> import locale
>>> locale.setlocale(locale.LC_TIME, 'pl_PL.UTF-8')
'pl_PL.UTF-8'
>>> time.strftime("%c")
'sob, 14 gru 2013, 00:27:09'

为什么Python在这种情况下不使用系统的环境变量？

Answer 1

因为默认情况下永远不会使用它们。您必须显式启用区域设置支持。

locale.setlocale(locale.LC_TIME, '')
