2.定义一个学生类Student,属性有age(年纪),name（姓名）,score（分数），实例化6个对象，放在集合中，有如下Student 对象

Sure, here's an example of how you can define a Student class in Python:

class Student:
    def __init__(self, name, age, score):
        self.name = name
        self.age = age
        self.score = score

To create 6 Student objects and store them in a collection, you can do the following:

students = []

# Create and add Student objects to the collection
student1 = Student("John", 18, 85)
students.append(student1)

student2 = Student("Emily", 17, 92)
students.append(student2)

student3 = Student("Michael", 19, 78)
students.append(student3)

student4 = Student("Sarah", 20, 90)
students.append(student4)

student5 = Student("David", 18, 88)
students.append(student5)

student6 = Student("Emma", 17, 95)
students.append(student6)

Now, you have 6 Student objects stored in the `students` collection. Each object has attributes like `name`, `age`, and `score` that you can access and manipulate as needed.
