Hey, i need to enter words to the list then count them an and print how many items in that list without counting duplicates

Joe janf :

You are learning a new language, and are having a competition to see how many unique words you know in it to test your vocabulary learning.

Write a program where you can enter one word at a time, and be told how many unique words you have entered. You should not count duplicates. The program should stop asking for more words when you enter a blank line.

For example:

Word: Chat Word: Chien Word: Chat Word: Escargot Word: You know 3 unique word(s)! ​ and

Word: Katze Word: Hund Word: Maus Word: Papagei Word: Schlange Word: You know 5 unique word(s)!
