[Django]-Python range() builtin function, erm… malfunctioning with Django

There’s nothing wrong with Django. You create a local variable range in the same scope (by assigning one). For instance range = None in the very last line of a function makes Python consider an occurrence of range in the first line of the same function a reference to that local variable. Since it doesn’t have a value assigned at that point, you get an UnboundLocalError.
