在python中一次排序列表的多个属性？

Question

我有一个代表一个人的元组（ID，总分，就业天数，同行分数）。

我决定将每个元组放在一个列表中，如下所示：

aList = [ aTup, bTup, cTup.....]

我想根据以下规则将人们从最好到最差排名。 规则如下：

1. People(in this case the tuples) are sorted based on their overall score.
-->If the overall score is the same, sort it by the number of days employed. 
-->If the days employed is the same, sort by peer score.
-->If the peer score is the same, sort by ID(the smaller ID gets preferenced.

python中有一个方法允许我实现这个吗？接近.sort（）方法的东西？

Answer 1

默认sort()实际上是为元组做的。您只需要确保元组的格式为(score, days_employed, peer_score, id)。
