The reverse flag can be set to sort in descending order. sorted 的用法: Help on built-in function sorted in module builtins: sorted(iterable, /, *, key=None, reverse=False) Return a new list containing all items from the iterable in ascending order. A custom key function can be supplie...
how can you sort a list of tuples by the second element? The key parameter will again come to the rescue. We can define our custom sort by defining our own key function. defcustom_sort(t):returnt[1]L=[("Alice",25),("Bob",20),("Alex",5)]L.sort(key=custom_sort)print(L)# ou...
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) ...
