$ and ^ are regular expression characters that have a special meaning: the caret means “require that the pattern matches the start of the string,” and the dollar sign means “require that the pattern matches the end of the string.”
For example consider the following url pattern
urlpatterns = patterns('',
url(r'^hello/$', hello),
)Without the dollar sign at the end it will match any url starting with hello like
- hello/satish
- hello/gandham/
- hello/satish/123/pqr
Note: use url(r'^$', my_homepage_view), to match root.
