本文介绍了一个简单的程序设计，用于帮助学习者记录并统计在新语言学习过程中遇到的独特词汇数量。程序能够接收用户输入的单词，并在用户输入空白行时停止，最终输出已录入的独特单词总数。

Q：
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)!

and

Word: Salam
Word: 
You know 1 unique word(s)!

word = input("Word: ")
list_word = []
num = 0
i = 0
while word:
  list_word.append(word)
  for n in range(len(list_word)):
    if len(list_word) == 1:
      pass
    else:
      if n != len(list_word) - 1:
        if list_word[len(list_word) - 1] == list_word[n]:
          num += 1
          list_word[n] = ""
  word = input("Word: ")
  i += 1
print("You know", len(list_word) - num, "unique word(s)!")
