# 面向对象的三大特点（封装，继承，多态）缺一不可。

# 列表使用
list = [1, 2, 3, 4, 55, 6, 7, 8, 10]

# 取值
list[-1]

# 查找元素出现次数
list.count(1)

# 查看重复原色
list.index(1)

# 增加元素
list.append(19)

# 指定位置添加元素
list.insert('L')

# 删除
del list[6]

# pop
list.pop(2)
num.pop(3)

# 删除指定元素
list.remove(3)

# reserse() 翻转
list.reserse()

# 切片
list[:3]
list[1:5:2] # 步长为2
list[::2]
