Question

使用Jinja2和Pyramid在i18n上使用Python。似乎有一个问题，知道它应该如何翻译%%。 ~~我开始怀疑这个bug是在Jinja2中。~~

所以我做了一些调查，看起来问题更多的是gettext而不是jinja2，如repl所示

>>>gettext.gettext("98%% off %s sale") % ('holiday')
'98% off holiday sale'
>>>gettext.gettext("98%% off sale")
'98%% off sale'

>>>gettext.gettext("98% off %s sale") % ('holiday')
Traceback (most recent call last):
  Python Shell, prompt 13, line 1
TypeError: %o format: a number is required, not str

这似乎是鸡/蛋的问题。

如果gettext翻译%% - ＆gt; ％然后格式化程序在参数替换期间就会爆炸。
如果gettext没有翻译%% - ＆gt; ％然后当没有调用格式化程序时（没有插入的参数），那么%%就会泄漏。

所有这些意味着翻译人员（大多数不是计算机程序员）必须非常小心他们如何进行翻译，每个人都需要非常小心包含％的翻译。

似乎我们这样做是错误的（不知何故）并且应该有一个更直接和统一的格式来做这件事。现在我们只是通过简单地注入一个％作为格式参数来应对。

有没有更好的方法来做到这一点，还是这样做得好？

底部有一个.po文件

单元测试几乎说明了一切，为什么最后一个断言失败了？这是Jinja2的错误，还是我需要以不同的方式解决这个问题。

class Jinja2Tests(TestCase):

    def test_percent_percent(self):
        """ i18n(gettext) expresses  98% as 98%% only in some versions of jinja2 that has not
            worked as expected.  This is to make sure that it is working. """
        env = Environment(extensions=['jinja2.ext.i18n'])
        lang = gettext.translation('messages', path.abspath(path.join(path.dirname(__file__), 'data')))
        env.install_gettext_translations(lang)

        template = env.from_string(source="{{ _('98%% off %(name)s sale') | format(name='holiday') }}")
        result = template.render()
        self.assertEqual('98% off holiday sale(translated)', result)

        template = env.from_string(source="{{ _('98%% off sale') }}")
        result = template.render()

        # THE LINE BELOW FAILS WITH:
        # AssertionError: '98% off sale(translated)' != u'98%% off sale(translated)'
        self.assertEqual('98% off sale(translated)', result)

要将MO文件编译为PO文件以运行上述代码。
