如何在Python 3中仅对嵌套列表中的子列表的某些元素进行排序

Question

I have a nested list. For example:

data=[['Alan', 8, 4, 5], ['Jog', 10, 1, 2], ['Rhys', 7, 8, 8], ['Sam', 7, 8, 9], ['Tom', 5, 6, 9], ['Tommo', 5, 4, 6]]

Now I want to sort the numbers within the sub-lists into descending order and finally arrange the nested list into alphabetical order in Python 3.

So output data should be:

[['Alan', 8, 5, 4], ['Jog', 10, 2, 1], ['Rhys', 8, 8, 7], ['Sam', 9, 8, 7], ['Tom', 9, 6, 5], ['Tommo', 6, 5, 4]]

where numbers in Rhys, Sam, Tom and Tommo have been reordered into descending order.

Answer 1

您可以使用列表推导：

[[list[0]] + sorted(list[1:], reverse=True) for list in sorted(data)]
