We store multiple values using list and tuple data structures in Python. We use the indices to state the position or location of that stored value. In Python, index values start from 0 untilthe length of tuple -1.For example, in the image above, we had a tuple containing three values (...

Learn the differences between lists and tuples in Python. Tuples are great for creating Value Objects. Lists are for storing a collection of value objects.
各位读者大大们大家好,今天学习python的Lists、Tuples、Sets集合操作,并记录学习过程欢迎大家一起交流分享。 首先新建一个python文件命名为py3_collections.py,在这个文件中进行字符串操作代码编写(如下为代码,文后有图片显示运行效果): 代码语言:javascript
lists,tuples and sets of Python (python2.7.x) Lists 列表 列表是一个有序序列(集合),可变的(可以修改),可以理解为其他语言中的数组类型,但是列表更灵活更强大。 列表由方括号[]来定义的,它的元素可以是任意类型或对象,一个列表中可以包含混合元素。
for element in my_list: print (element) Tuples 元组 元组类似于列表,但它是固定长度和不可变的。因此,既不能更改tuple中的值,也不能在tuple中添加或删除值。元组通常用于不需要更改的值的小集合,如IP地址和端口。元组由圆括号表示,而不是方括号

Empty tuple acts as a singleton, that is, there is always only one tuple with a length of zero. When creating an empty tuple Python points to already preallocated one, in such way that any empty tuple has the same address in the memory. This is possible because tuples are immutable and...
