一、列表(list)

  • list列表是由中括号 [ ]括起来,逗号‘,’ 去分割每个元素
  • 列表中的每个元素可以是所有数据类型的数据:数值、字符串、列表(再内嵌列表)、字典、布尔值
  • 列表是有序的,元素可被修改 (值变,地址不变)

1. 下标、切片 获取列表的某一个或者多个元素

# list,索引,切片取值my_list=[123,'yexiang',['美女',18],False]#索引取值print(my_list[0]) # 123print(my_list[2]) # ['美女', 18]# 切片取值 (左闭右闭开) [a b)print(my_list[0:])   # [123, 'yexiang', ['美女', 18], False]print(my_list[0:3])  # [123, 'yexiang', ['美女', 18]]print(my_list[0:-1]) # [123, 'yexiang', ['美女', 18]]
