python - 当 "include"ing Django URL 模式时，'function' 对象不可订阅？

Question

我正在制作一个 Django 网站，我正在看一个教程 http://youtube.com ，我遇到了问题。这是我的 urls.py 脚本:

from django.conf.urls import patterns, include, url

# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()

urlpatterns = patterns('',
    (r'^', include['FirstBlog.apps.homepage.urls']),
    # Examples:
    # url(r'^$', 'FirstBlog.views.home', name='home'),
    # url(r'^FirstBlog/', include('FirstBlog.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    # url(r'^admin/', include(admin.site.urls)),
)

我的输出:

请帮忙？

此外，如果您有我可以遵循的好的教程，请将其链接给我!此外，我更愿意将 Mamp Pro 用于数据库。帮助 n00b？

include 是一个函数；你正在订阅它，就好像它是一个列表。

例如:

apples = [ 'Granny Smith', 'Russet' ]
red_apple = apples[1]    # <-- Subscripting a list

因为函数不能被下标，所以你得到了你发布的错误。但是，从注释示例中可以看出，您应该使用 () 语法调用函数:

(r'^', include('FirstBlog.apps.homepage.urls'))
#             ^                              ^
