Question

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)

Answer 1

Program:

# using set() to avoid duplication

words=set()
  
while(True):
   word=input("Word: ")
   if(word==""):
       break;
   words.add(word)

uniqueWords=str(len(words))

print("You know", uniqueWords,"unique word(s)")
