Upper Or Lower Menu

Read a word with the prompt Word: , then show a three-item menu: 1) Upper case prints the word in capitals using .upper(), 2) Lower case prints it in small letters using .lower(), 3) Quit prints Goodbye! and leaves the loop, and anything else prints Unknown choice - try again.. Read the choice with the prompt Choice: and strip it. Input: the word, then one choice per line ending with 3. Prompts are part of the output, so the word prompt sits in front of the first menu line and each result follows Choice: .

Expected Output:

Word: 1) Upper case↵
2) Lower case↵
3) Quit↵
Choice: HELLO↵
1) Upper case↵
2) Lower case↵
3) Quit↵
Choice: hello↵
1) Upper case↵
2) Lower case↵
3) Quit↵
Choice: Goodbye!↵

= newline. The output ends with a newline — print one after the last line.
