Syntax Error in the urls.py in Django

Question

I am trying to add a few urls in my urls.py.

urls.py

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'Permissions.views.home', name='home'),
    # url(r'^Permissions/', include('Permissions.foo.urls')),
     #url(r'^Permissions$', include('Permissions.Authenication.urls')),
     url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
     url(r'^admin/', include(admin.site.urls)),
     url(r'^$',RedirectView.as_view(url='/welcome/'),
)

urlpatterns += patterns('',
     url(r'^register/$', 'drinker.views.DrinkerRegistration',name='DrinkerRegistration'),
     url(r'^welcome/$','drinker.views.DrinkerWelcome',name='DrinkerWelcome'),
     url(r'^home/(?P<userpk>[^/]+)/$','drinker.views.DrinkerHome',  name='DrinkerHome'),     
)

Error:

Traceback:

Exception Type: SyntaxError at /
Exception Value: invalid syntax (urls.py, line 17)

Not sure where the error is... Need some help...

You're missing a parenthesis and have an extra comma:

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'Permissions.views.home', name='home'),
    # url(r'^Permissions/', include('Permissions.foo.urls')),
    # url(r'^Permissions$', include('Permissions.Authenication.urls')),

    url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', RedirectView.as_view(url='/welcome/')) #Error was here
)

You have another trailing comma in your second half:

urlpatterns += patterns('',
    url(r'^register/$', 'drinker.views.DrinkerRegistration',name='DrinkerRegistration'),
    url(r'^welcome/$','drinker.views.DrinkerWelcome',name='DrinkerWelcome'),
    url(r'^home/(?P<userpk>[^/]+)/$','drinker.views.DrinkerHome', name='DrinkerHome') # Comma was here     
)
