Delete more than 1 user from the database

Question

Hi All,
I have a list of users in a file and i want to write a script to delete all these
users from my database.
I have tried deleting users using:
drop user user1,user2,user3..... but it doesn't seem to work.
Can anyone suggest how do i read the users from the file and delete them one by one
