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) which should
In this tutorial, we’ll utilize the functools module to create a comparator as a function to sort a list. Therefore, let’s first import the module and then create a sample string list.import functools # importing functools module str_list = ["Statistics", "Data", "Science", "Python",...
