我在里面经常看得到字符串外加一个_()，如_("right-click for menu")。
请问这里"_"是什么？是函数名吗？可是我没找到这个函数的声明啊。
谁知道这个函数的声明在哪里吗？

谢谢了。

yes, it is a function name
the following is copied from $PYTHONHOME/tools/i18n/pygettext.py:

    import fintl
    _ = fintl.gettext

这是gettext使用的，不是python的函数， 在使用gettext进行国际化的PHP程序中，也可看到_('xxx')等内容

更详细信息可在google查询

thanks for your reply.
but i still wonder where is the definition of the "_" function.
following your desc, i tried the code as follows:

>>> import gettext
>>> _("test")
Traceback (most recent call last):
  File "", line 1, in ?
NameError: name '_' is not defined
>>> gettext._("test")
Traceback (most recent call last):
  File "", line 1, in ?
AttributeError: 'module' object has no attribute '_'

as can be seen from the result, i don't think the "_" function is
declared in the gettext module.

so, where is it?

Thanks

do this:

    from gettext import gettext as _

_ is just a shortcut alias for gettext (or *gettext)
which can be from standard library or  fintl.py
