The example sorts the nested tuples initally by their first elements, then by their second. vals.sort(key=lambda e: e[1]) 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), ...

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....

是官方版本的解释器:CPython。是使用C语言开发的,所以叫CPython。在命令行下运行python就是启动CPython解释器。 CPython是使用最广的Python解释器。教程的所有代码也都在CPython下执行。 IPython IPython是基于CPython之上的一个交互式解释器,也就是说,IPython只是在交互方式上有所增强,但是执行Python代码的功能和CPython...
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 = ...

In this lesson, we have learned how to dopython tuple sorting. We have given different examples forpython tuple sort. Do not forget, by default tuples can not be changed, they are immutable. But here we are doing a python trick to sort a tuple....
