姓名name、学号ID、性别gender、专业majoy、出生年月date、兴趣爱好hobby

好的，那么我来为student类添加这些属性和方法：

class Student:
    def __init__(self, name, ID, gender, major, date, hobby):
        self.name = name
        self.ID = ID
        self.gender = gender
        self.major = major
        self.date = date
        self.hobby = hobby
        
    def get_name(self):
        return self.name
    
    def set_name(self, name):
        self.name = name
        
    def get_ID(self):
        return self.ID
    
    def set_ID(self, ID):
        self.ID = ID
        
    def get_gender(self):
        return self.gender
    
    def set_gender(self, gender):
        self.gender = gender
        
    def get_major(self):
        return self.major
    
    def set_major(self, major):
        self.major = major
        
    def get_date(self):
        return self.date
    
    def set_date(self, date):
        self.date = date
        
    def get_hobby(self):
        return self.hobby
    
    def set_hobby(self, hobby):
        self.hobby = hobby

这样，你的student类就拥有了姓名、学号、性别、专业、出生年月、兴趣爱好等属性，同时也有了对应的getter和setter方法，可以方便地获取和修改对象的属性。
