You can't nest tags like that.
There are various options - have you tried defining a string in your
view which is ":" + limit, and passing that to the template? Or
perhaps limiting news_list in your view?
Or, you could define a custom filter which takes a value and returns a
list sliced to that length. Something like (untested):
def slice_to_var(lst, lngth):
return lst[:lngth]
