串列 (二)

本帖最後由 tonyh 於 2022-4-23 18:14 編輯

假設有一串列其內容如下:
list=[12,-3,-50,32,25,11]

試以sort()、reverse()、len()、pop()、append()、insert()等函式,完成如下操作:



  1. list=[12,-3,-50,32,25,11]
  2. print("排序前:",list)
  3. list.sort();
  4. print("排序後(遞增):",list)
  5. list.reverse();
  6. print("排序後(遞減):",list)
  7. print("元素數量:",len(list))
  8. list.pop()
  9. print("pop掉一元素",list)
  10. list.append(-20)
  11. print("append一元素",list)
  12. list.insert(4,0)
  13. print("insert一元素",list)
