串列 (二)

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

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

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