USE PYTHON FOR THIS!3.13 LAB: Extracting Passwords (files and lists) The Linux operating system is a very popular server OS. A network administrator has to protect the login/password files stored on the servers. In Linux there are two important files: /etc/passwd And it contains rows that look like this: root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin:/sbin/nologin daemon:x:2:2:daemon:/sbin:/sbin/nologin adm:x:3:4:adm:/var/adm:/sbin/nologin ftp:x:14:50:FTP User:/var/ftp:/sbin/nologin user1:x:15:51:User One:/home/user1:nologin user2:x:15:51:User One:/home/user1:nologin user3:x:15:51:User One:/home/user1:nologin This file contains login information. It's a list of the server's accounts that has userID, groupID, home directory, shell and more info. And the second file /etc/shadow, contains rows that look like this: root:$1$TDQFedzX$.kv51AjM.FInu0lrH1dY30:15045:0:99999:7::: bin:*:14195:0:99999:7::: daemon:*:14195:0:99999:7::: adm:*:14195:0:99999:7::: ftp:*:14195:0:99999:7:::…2.11 Two opposing views on comments in programs could be stated as follows: (a) A program should always contain elaborate comments to make it readable and maintainable. (b) A program should be as much as possible self-documenting, with comments added sparingly only where the code itself might be unclear. Discuss these two viewpoints from the point of view of language design. What design features might aid one viewpoint but not the other? What might aid both?
