使用Python对数据进行排序

我对Python一无所知，下面是我的代码片段

class student:
    def __init__(stu, code, name, number):
        stu.code = code
        stu.name = name
        stu.number = number    

student = [
stu("901", "Joh Doe", "123456")
stu("902", "Mary Mount", "566665")
stu("903", "David Lee", "394624")
]

我想把下面最后的数据从高到低排序，我可以知道怎么做吗

您可以使用

排序

功能对学生进行排序（我假设您是按第三个元素的降序排序）

student = [
("901", "Joh Doe", "123456"),
("902", "Mary Mount", "566665"),
("903", "David Lee", "394624")
]

print sorted(student, reverse=True, key = lambda x: int(x[2]))

[('902', 'Mary Mount', '566665'), ('903', 'David Lee', '394624'), ('901', 'Joh Doe', '123456')]

902         Mary Mount         566665
903         David Lee          394624
901         Joh Doe            123456

student = [
("901", "Joh Doe", "123456"),
("902", "Mary Mount", "566665"),
("903", "David Lee", "394624")
]

print sorted(student, reverse=True, key = lambda x: int(x[2]))

[('902', 'Mary Mount', '566665'), ('903', 'David Lee', '394624'), ('901', 'Joh Doe', '123456')]
