NoReverseMatch error happened while redirecting to another url from views.py in django

I am trying to redirect user after the signup is done and getting the below error.

Reverse for 'verificationsent' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

urls.py --

urlpatterns = [
    url(r'^ciasadmin/', admin.site.urls),
    url("^$", views.homepage, name="home"),
    url(r'^account/', include('accounts.urls')),
]

accounts/urls.py -- 

from django.conf.urls import url
from . import views


urlpatterns = [
    url(r"^signup/$", views.signup, name="account_signup"),
    url(r'^verificationsent/$', views.verificationsent, name='account_verificationsent'),
    url(r'^activate/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$',views.activate, name='activate'),
]

views.py -- 

return redirect('verificationsent')

I have followed the solutions from the below SO references but didn't work.

Redirect with parameters. NoReverseMatch at /test/

Any help is highly appreciated. Thanks in advance.

You should not use direct url reference statements as per best practice. Always reverse the urls

return redirect(reverse('account_verificationsent'))

If you have a namespace for your app then you have to use that in reverse also.
