Using the URLconf defined in acs.urls, Django tried these URL patterns, in this order:

  1. [name='index']
  2. education [name='education']
  3. contact [name='contact']
  4. intro_course [name='intro_course']
  5. rw [name='rw']
  6. rw2 [name='rw2']
  7. eca/ [name='eca_selector']
  8. ^eca/(?P<rule>[0-9]+)/(?P<initial_conditions>[\w]+)/$ [name='eca']

  13. ^fully_connected_interactive/$ [name='fully_connected_interactive']
  14. ^flocking/$ [name='flocking']
  15. admin/

The current path, intro_course_b, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
