Thanks for pointing out the mistakes. Your points are right. So I am trying to revise it,

for line in file_open:
         print (line_word)

To store them the best way is to assign a blank list and append but is there any alternate
method for huge data it becomes tough as the list becomes huge if any way variables may be assigned.
