[Answered ]-Django url regular expression repeats in URL

add $ to the end

url(r’^about/$’,views.about , name = ‘about’),

More generally, about/anything/ will match as well. The $ indicates the end of a string (or in this case url), just like ^ indicates the start of it. Checking against r'^about/' only checks that the url starts with about/, not where it ends.

That is generally the behaviour you want when you include another url config, like admin/. In that case, the pattern shouldn’t end after admin/, but there should be another part that matches a configured url in the included file. But if your pattern is a single view, you generally want the url to end after the end of the pattern, that’s when you include the $, e.g. r'^about/$'.
