请使用此序列化 Python 3.11，目标是

{"name": "One", "quantity": 2, "students":[{"first_name": "Geeky", "last_name": "Guy"},{"first_name": "GFG", "last_name": "ocks"}] }

import json
 
class Student():
    def __init__(self):
      pass
 
 
class Team():
    def __init__(self):
        pass
  
student1 = Student()
student1.first_name='Geeky'
student1.last_name='Guy'
student2 = Student()
student2.first_name='GFG'
student2.last_name='ocks'
team = Team()
team.name='One'
team.quantity=2
team.students=[]
team.students.append(student1)
team.students.append(student2)

 
# Serialization
json_data = json.dumps(team.__dict__)
print(json_data)

打印下一个错误
