You can access tuple items by referring to the index number, inside square brackets: ExampleGet your own Python Server Print the second item in the tuple: thistuple = ("apple","banana","cherry") print(thistuple[1]) Try it Yourself » ...

在Python中,字典列表是一种常见的数据结构,用于存储多个字典的集合。每个字典代表一条记录,字典中的键值对表示记录的属性和对应的值。提取字典列表中的元素可以通过多种方式实现,具体取决于你想要提取的信息。 基础概念 字典(Dictionary):一种可变容器模型,且可存储任意类型对象。字典的每个键值对用冒号分割,每个对之间...
To access the items in a sublist, simply append an additional index:索引也是根据嵌套来的>>> x[1] ['bb', ['ccc', 'ddd'], 'ee', 'ff'] >>> x[1][0] 'bb' >>> x[1][1] ['ccc', 'ddd'] >>> x[1][2] 'ee' >>> x[1][3] 'ff' >>> x[3] ['hh', 'ii'] >>...

Tuple Items Tuple items are ordered, unchangeable, and allow duplicate values. Tuple items are indexed, the first item has index[0], the second item has index[1]etc. Ordered When we say that tuples are ordered, it means that the items have a defined order, and that order will not chan...

() is a special token and denotes empty tuple. In 3, as you might have already figured out, there's a missing comma after 5th element ("that") in the list. So by implicit string literal concatenation, >>> ten_words_list ['some', 'very', 'big', 'list', 'thatconsists', 'of'...
