My version (using [:]) replaces the *contents* of the original list, but  
the list itself remains the same object.
Yours (without the [:]) reasigns a new list to the old name; the  
*contents* are the same as the former version, but now the name "lines"  
refers to a different list.
Depending on the context, the difference may be important or not.
