在Python中

在Python中，使用set()關鍵字set並使用set 。例如：

  names = set()
  names.add("Michele")
  names.add("Robin")
  names.add("Michele")
  print(names)

輸出將是；

  set(['Michele', 'Robin'])

您可以設置一個集合，幾乎可以對列表執行任何操作（要求“第三個元素”之類的東西除外）。請參閱有關集合的Python文檔，以獲取可以對集合進行操作的完整列表。

您可以很容易地將列表轉換為集合，然後將集合轉換為列表：

  names = ["Michele", "Robin", "Sara", "Michele"]
  names = set(names)
  names = list(names)
  print(names)

15 Reverse Word Order
Exercise 15 and Solution

Write a program (using functions!) that asks the user for a long string containing multiple words. Print back to the user the same string, except with the words in backwards order. For example, say I type the string:

  My name is Michele

Then I would see the string:

  Michele is name My

shown back to me.
