排序元组 Python

Sort Tuples Python(排序元组 Python)

问题描述

我的 Blender python 代码中有一个元组列表

I have a list of tuples in my Blender python code

scores=[(1489,"Sean"), (2850,"Bob"), (276,"Crap Player"), (78495, "Great Player"), (8473, "Damian"), (4860, "Andy"), (0, "Stephen")]

我正在尝试使用它按分数对它们进行排序

I'm trying to sort them by their score by using this

sorted(scores, key=lambda score: score[0], reverse=True)

但这不起作用.我不知道为什么.有什么建议吗?

but this is not working. I have no idea why. Any tips?

我考虑过也许更好的实现是创建一个新的 Score 类，其中包含字段 name 和 score

I've considered maybe a better implementation is to create a new Score class with fields name and score

感谢大家的快速回复

sorted 方法没有给我任何错误，但没有排序.我使用了 sort() 并且它有效.

it was giving me no errors with the sorted method but was not sorting. I used the sort() and it works.

我认为 python 在 Blender 中可能有点奇怪?

I think python is just a little weird in Blender maybe?

谢谢！

推荐答案

随便做吧:

print sorted(scores, reverse=True)
[(78495, 'Great Player'), (8473, 'Damian'), (4860, 'Andy'), (2850, 'Bob'), (1489, 'Sean'), (276, 'Crap Player'), (0, 'Stephen')]

如果你想就地排序，你可以使用 scores.sort(reverse=True)，顺便说一下，在元组列表的情况下，排序函数默认按第一项排序，第二个项目..

you can use scores.sort(reverse=True) if you want to sort in place, and by the way the sort function in case of list of tuple by default sort by first item , second item ..
