方法1.用List的成员函数sort进行排序 方法2.用built-in函数sorted进行排序(从2.4开始) 这两种方法使用起来差不多,以第一种为例进行讲解: 从Python2.4开始,sort方法有了三个可选的参数,Python Library Reference里是这样描述的 cmp:cmp specifies a custom comparison function of two arguments (iterable elements) ...
Sort the list based on how close the number is to 50: defmyfunc(n): returnabs(n -50) thislist = [100,50,65,82,23] thislist.sort(key =myfunc) print(thislist) Try it Yourself » Case Insensitive Sort By default thesort()method is case sensitive, resulting in all capital letters ...

<Python直播课 点击跳转> 2、sort()的理解使用 sort() 函数用于对原列表进行排序,如果指定参数,则使用比较函数指定的比较函数。 语法如下: list.sort(cmp=None, key=None, reverse=False) 参数: cmp – 可选参数,如果指定了该参数会使用该参数的方法进行排序。

numbers is emptyfind max numberSortingSorted 在状态图中,初始状态为Sorting,表示正在进行排序操作。当数字列表为空时,进入Sorted状态,表示排序完成。如果数字列表不为空,则回到Sorting状态,继续查找最大值。 结语 通过本文的介绍,我们了解了一种不使用sort方法的方式来实现对数字的排序。这种方法虽然不如sort来得简洁...
