2 of the tuples have3as the second element, and since we set thereverseargument toTrue, the tuple with the greater 3rd element gets moved to the front. The last tuple in the list is the one with the lowest second element. #Sort a list of tuples by multiple elements using operator.it...
Python provides us with some built-in sorting methods. While using the sorting methods, we need to pass a method to the method which will swap the element to the second element of tuple. Program 1: Using sort() method # Python program to sort a list of tuples by second item# Creating...

原文:https://realpython.com/python-sort/ 排序问题是所有程序员一定会遇到的问题,Python内置的排序工具sort()和sorted()功能强大,可以实现自定义的复杂式排序。平时我们使用两个函数可能没有仔细研究过它们的区别,随想随用了。但实际上二者还是有很大的去别的,在一些场景中不同互换使用。
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....

%%add_method_toCarddefto_tuple(self):return(self.suit,self.rank) 我们可以使用这个方法来编写__lt__。 %%add_method_toCarddef__lt__(self,other):returnself.to_tuple()<other.to_tuple() 元组比较会比较每个元组的第一个元素,这些元素表示花色。如果它们相同,则比较第二个元素,这些元素表示点数。
The race director now informs you that every forty-second runner to cross the finish line will receive a free gym bag. That’s a problem! By using.sort(), you changedrunnersirreversibly. There’s no way to recover the original list of runners in the order they finished and find every fo...
