Python 名称错误 : global name 'any' is not defined

Question

我的生产服务器出现以下错误:

Traceback (most recent call last):

 File "/usr/lib/python2.4/site-packages/django/core/handlers/base.py", line 89, in get_response
response = middleware_method(request)
 File "myproject/middleware.py", line 31, in process_request
if not any(m.match(path) for m in EXEMPT_URLS):

NameError: global name 'any' is not defined

服务器正在运行 python 2.6，并且在开发中没有出现这个错误。违规代码在 middleware.py 中:

...
if not request.user.is_authenticated():
        path = request.path_info.lstrip('/')
        if not any(m.match(path) for m in EXEMPT_URLS):
            return HttpResponseRedirect(settings.LOGIN_URL)

我是否应该重写这个 any 函数来解决这个问题？

Answer 1

您实际上是在 Python 2.4 上运行，它没有内置的 any。

如果你需要定义自己的any，很简单:

try:
    any
except NameError:
    def any(s):
        for v in s:
            if v:
                return True
        return False
