1.clear()：清空列表
name_List = ['jch', '小明', '小红', '小王']
name_List.clear()
print(name_List)            #[]

2.逆置：reverse()
name_List = ['jch', '小明', '小红', '小王']
name_List.reverse()
print(name_List)         #['小王', '小红', '小明', 'jch']

3.排序：sort()--语法：列表序列.sort( key=None, reverse=False)
# 注意：reverse表示排序规则，reverse = True 降序， reverse = False 升序（默认）
name_List1 = [1, 25, 6, 9, 46]
name_List1.sort()
print(name_List1)       #[1, 6, 9, 25, 46]
name_List1.sort(reverse=True)
print(name_List1)       #[46, 25, 9, 6, 1]

4. 复制--函数：copy()
name_List = ['jch', '小明', '小红', '小王']
name_List1 = [1, 25, 6, 9, 46]
name_List = name_List1.copy()
print(name_List)        #[1, 25, 6, 9, 46]
