在尝试使用Python运行Django服务时遇到了一个错误，具体表现为'ImproperlyConfigured'异常，指出URLconf '__main__'没有包含任何模式，可能由循环导入引起。错误的根本原因是`urlpatterns`定义时缺少了's'，导致模块无法迭代。

django.core.exceptions.ImproperlyConfigured: The included URLconf '__main__' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

我的错误原因为：

urlpatterns = (
    url(r'^$', index),
)

urlpatterns少写了一个s
