1.2.3: Tuples 元组 元组是不可变的序列,通常用于存储异构数据。 Tuples are immutable sequences typically used to store heterogeneous data. 查看元组的最佳方式是将其作为一个由多个不同部分组成的单个对象。 The best way to view tuples is as a single object that consists of several different parts....

By providing an anonymous function which returns the second element of the tuple, we sort the tuples by their second values. $ ./sort_elem_idx.py [(-1, 3), (0, -2), (1, 1), (3, 5), (4, 0)] [(0, -2), (4, 0), (1, 1), (-1, 3), (3, 5)] ...
tuple=(1,2,'hi')print(len(tuple))## 3print(tuple[2])## hituple[2]='bye'## NO, tuples cannot be changedtuple=(1,2,'bye')## this works 要创建 size-1 元组,孤立元素必须后跟英文逗号。 tuple=('hi',)## size-1 tuple 这在语法中十分有趣,但要将元组与用括号括住表达式的普通情况区...

You have seen that an element in a list can be any sort of object. That includes another list. A list can contain sublists, which in turn can contain sublists themselves, and so on to arbitrary depth.Consider this (admittedly contrived) example:...
To effectively sort nested tuples, you can provide a custom sorting key using the key argument in the sorted() function.Here’s an example of sorting a list of tuples in ascending order by the second element in each tuple: my_list = [(1, 4), (3, 1), (2, 5)] sorted_list = ...
