We can sort a list of numbers simply using thesort()method or thesorted()function. However, we cannot do so with a list of objects created using custom classes. In this article, we will discuss how we can sort a

sort(); print("List : ") print(aList)以上实例输出结果如下:List : ['123', 'Facebook', 'Google', 'Runoob', 'Taobao']以下实例降序输出列表:实例 #!/usr/bin/python # -*- coding: UTF-8 -*- # 列表 vowels = ['e', 'a', 'u', 'o', 'i'] # 降序 vowels.sort(reverse=True) ...
Python has two basic function for sorting lists:sortandsorted. Thesortsorts the list in place, while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandreverse. Thekeytakes a function which will be used on each value in the list being ...

Python的列表对象具有一个名为sort()的方法，它可以在原地对列表进行排序，而不会创建新的列表。默认情况下，它按升序排序。让我们看看它的用法：original_list = [3, 1, 2, 5, 4]original_list.sort()print(original_list) # 输出 [1, 2, 3, 4, 5]与sorted()函数不同，sort()方法不返回新列表，...
在Python编程中，sort函数是一个非常强大的工具，用于对列表进行排序。它可以根据特定的排序规则，对列表元素进行升序或降序排列。接下来，我们将详细介绍sort函数的使用方法。语法 sort函数的基本语法为：list.sort(key=None, reverse=False)其中，key和reverse都是可选参数。参数解析 key：用于指定一个函数，根据该...
