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 » ...
We use index numbers to access tuple items. For example, languages = ('Python', 'Swift', 'C++') # access the first item print(languages[0]) # Python # access the third item print(languages[2]) # C++ Access Tuple Items Tuple Cannot be Modified Python tuples are immutable (unchangeabl...
Also, you can access any element of the list by its index which is zero based.third_elem = mylist[2]There are some similarities with strings. You can review the Python programming basics post.Mutable Lists/改变列表Lists are mutable because items can be changed or reordered....
(element1, element2, ... , elementn) 从存储内容上看,元组可以存储整数、实数、字符串、列表、元组等任何类型的数据,并且在同一个元组中,元素的类型可以不同,在这个元组中,有多种类型的数据,包括整形、字符串、列表、元组。例如: ("test.com.cn",1,[2,'a'],("abc",3.0)) ...
一、数据容器简介 Python 中的 数据容器 数据类型 可以 存放多个数据 , 每个数据都称为 元素 , 容器 的 元素 类型可以是任意类型 ; Python 数据容器 根据 如下不同的特点 : 是否允许元素重复...是否允许修改是否排序分为五大类 : 列表 List 元组 tuple 字符串 str 集合 set 字典 dict 下面从 列表 List 开...
