        url(r'^Financial_Development/',views.Financial_Development,name='Financial_Development'),
    path('admin/', admin.site.urls),
]

urlpatterns=[
url(r'^$',views.basic_skeleton,name='basic_skeleton'),
url(r'^Personal_Development/$',views.Personal_Development,name='Personal_Development'),
url(r'^Financial_Development/$',views.Financial_Development,name='Financial_Development'),
url(r'^Professional_Development/$',views.TheProfessionalResourcesListViewCBV.as_view(),name='Professional_Development'),
url(r'^Resources_Professional/$',views.Resources_Professional,name='Resources_Professional'),

url(r'^TheProfessionalResourcesCBV_list/',views.TheProfessionalResourcesListViewCBV.as_view(),name='list')
