In this example, you create a list of countries represented by string objects. Because lists are ordered sequences, the values retain the insertion order.Note: To learn more about the list data type, check out the Python’s list Data Type: A Deep Dive With Examples tutorial....
The tuples are more memory efficient than the list because tuple has less built-in operations. Lists are suitable for the fewer elements whereas tuples are a bit faster than the list for the huge amount of data. Tuple = (1,2,3,4,5,6,7,8,9,0,5485,87525,955,3343,53234,6423,623456...

Finally, let us list down all thedifferences between lists and tuples in Python, discussed above. List are created with square brackets and tuples are created with round bracket. Lists are mutable whereas Tuples are immutable. Tuples offer a little more memory efficient solution. ...
list1 = ['Hello', 'Python']print(tuple(list1)) ('Hello', 'Python') 将字典转换为元组 dict1 = {'Hello': 'Python', 'name': 'pink'}print(tuple(dict1)) ('Hello', 'name') 将集合转换为元组 set1 = {'Hello', 'Python', 'name', 'pink'}print(tuple(set1)) ...
python tuple类型数据增加 python中的tuple类型 元组是跟列表非常类似的一种容器类型,但是列表是可变的,形式是list[ ],元组是不可变的,形式为tuple( )。 1.创建元组。 元组的创建方法与列表类似,只有一点不同,元组内至右一个元素的时候需要在元素后面加上一个逗号(,)。因为元组的形式是用...
Python学习笔记_List&Tuple Someting about Lists mutation View Code 这里的赋值需要注意: b = a ,则a, b指向同一块内存,对a[1]或者b[1]赋值, 都可以改变这个list; b = list(a), 则a, b指向不同的内存。 又如: x = range(5) y = x

在Python中,通过Tuple可以很方便地进行多值的交换。这种操作在实际编程中非常常见,特别是在排序算法等场景下。例如: ```python a = 1 b = 2 a, b = b, a ``` 通过这种方式,可以很简洁地实现a和b的值交换,非常方便和高效。 9. Tuple vs List Tuple和List在Python中都是非常常见的数据结构,它们都有自...
