Django urls.py 语法错误（可能是导入问题？）

Question

我正在使用 django 框架，但遇到错误。
这是我的 settings.py，INSTALLED_APPS

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'apps',
)

而且，这是我的 apps/ 目录。

apps/
    __init__.py
    qnaBoard/
        admin.py
        migrations/
        tests.py
        views.py
        urls.py
        __init__.py
        models.py
        urls.py

而且，这是我的 urls.py，它与 settings.py 位于同一目录中。

from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns('',
    url(r'^course/', include('apps.qnaBoard.urls')),
    url(r'^admin/', include(admin.site.urls)),
) 

我认为我遵循了正确的方法，但是它说找不到 apps.qnaBoard.urls，并引发语法错误。

这是回溯：

Traceback:

Exception Type: SyntaxError at /course/
Exception Value: invalid syntax (urls.py, line 4)

这是apps/qnaBoard/urls.py

from django.conf.urls import patterns, include, url
from django.contrib import admin
from apps.qnaBoard.views import showPost
from apps.qnaBoard.views import showQuestionThread
from apps.qnaBoard.views import writeReply
from apps.qnaBoard.views import writeQuestion
from apps.qnaBoard.views.import writeAnswer

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'campusmate.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),
    # need to be refactored when course router are attached.
    url(r'^([0-9]+)/([1-4])/([A-Za-z0-9]+)/article/list/', showPost.as_view()),
    url(r'^([0-9]+)/([1-4])/([A-Za-z0-9]+)/article/([0-9]+)/$', showQuestionThread.as_view()),
    url(r'^([0-9]+)/([1-4])/([A-Za-z0-9]+)/article/([0-9]+)/reply', writeReply.as_view()),
    url(r'^([0-9]+)/([1-4])/([A-Za-z0-9]+)/article/write/$', writeQuestion.as_view()),
    url(r'^([0-9]+)/([1-4])/([A-Za-z0-9]+)/article/write/([0-9]+)/$', writeAnswer.as_view()),
)

Answer 1

从网址中删除 .。

问题出在以下文件中：

文件名： apps/qnaBoard/urls.py

from apps.qnaBoard.views.import writeAnswer. 在那里，删除它。
