4. In lab4_p4.py a list items is declared and initialized with 6 words. Use join to create a string obtained by combining all the words in the list items separated by commas. Assign your string to a variable named favorite_things and print this string. Be sure to include a space after each comma in your answer so that favorite_things has value "raindrops, roses, whiskers, kittens, kettles, mittens". Do not modify the value of items.

Create a list with at least five (5) strings to be used as usernames.  Create a corresponding list of five (5) strings to be used as passwords (one for each username).    Invite the user to enter a username.  If it is in the list, invite them to enter a password.  If the password matches, print a welcome message using their username. If the user enters a username that is not on the list or enters a password that does not match, print an appropriate message to inform them.   For example if the usernames were matwood, wshakes, sking, rmunch, jrowlin and passwords were handmaids, hamlet, It, BeQuiet, Potter then entering sking followed by It would give a welcome message whereas entering sking followed by Hamlet would not.
