I was busy doing the Django tutorials and they explain how you can have url patterns which make it possible to pass information back to the functions in the view.py file. For example
urlpatterns = patterns('',
url(r'^some_view/(?P<number>\d+)', views.some_view, name = 'some_view')
and the integer in the url slot '(?Pnumber>\d+)' is passed to the some_view function in the file views.py. Apparently the d+ stands for decimal but what should it be if I want to pass a string variable back to the some_views function.
