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 ...
sorted(iterable,/, *, key=None, reverse=False) Return a new list containing all itemsfromthe iterableinascending order. A custom key function can be supplied to customize the sort order,andthe reverse flag can be set to request the resultindescending order. 2. 除了用operator之外我们也可以用...
sorted()sorts the elements of a list in ascending order. To sort a list of lists based on a specific element in each sublist, you can pass a custom sorting function to thekeyargument. In this article, I will explain how to sort a list of lists in Python by using thesort()method, a...

To sort the list in reverse order, you can use the reverse parameter for the list.sort(reverse=True) method. You can also provide a custom function to sort the list with your rules. For example, sort the list by odd and even elements or by the internal properties of an object in the...
