、str、dict、tuple、set等，如整形、bool是不可迭代的所以不能用作参数
insert(index,object)：列表中插入元素。...(是对列表索引位置的操作，而不是按元素将升序转为降序)
list_1 = [1,3,2,4]
list_2 = ["a","c","b","d"]
list_1.reverse()
list_2.reverse...a","c","b","d"]]
list_1.reverse()
print(list_1)
# 打印内容如下
[['a', 'c', 'b', 'd'], 4, 2, 3, 1]
sort()：升序排列...list_1 = [1,4,88,3,2,77]
list_1.sort() # 默认升序排列
print(list_1)
# 打印内容如下:
[1, 2, 3, 4, 77, 88]
list..._1 = [1,4,88,3,2,77]
list_1.sort(reverse = True) # 降序排列
print(list_1)
# 打印内容如下:
[88, 77, 4, 3, 2,
