Python Django AttributeError:“tuple”对象没有属性“get”

我在学习教程时很难得到正确的回答 无论何时运行服务器，我都无法进入视图。请帮我检查一下代码。我不确定我正在使用的django版本和教程正在使用的版本是否有问题，因为我注意到教程中的版本使用了from django.url导入路径，但当我启动应用程序时，它来自django.conf.url。这是不同的，我很困惑

这是我的民意测验/观点。py

from django.http import HttpResponse

def index(request):
    return HttpResponse("You did it this time!,"),

这是我的民意测验/url.py 这是我的mysite/url.py

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^polls/', include("polls.urls")),
    url(r'^admin/', admin.site.urls),
]

在视图中的return语句中留下了一个尾随逗号。去掉那个，你会没事的

准确地说，请从

返回HttpResponse这次是你做的

到

返回HttpResponseYou这次这么做了

非常感谢你帮助我。它解决了我愚蠢的错误。下次会认真写的。哇。谢谢你。解决了大量的头痛问题。

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^polls/', include("polls.urls")),
    url(r'^admin/', admin.site.urls),
]
