在python中使用for循环创建多个类对象

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age
    
    def greet(self):
        print(f"Hello, my name is {self.name} and I am {self.age} years old.")

people_data = [
    {"name": "Alice", "age": 25},
    {"name": "Bob", "age": 30},
    {"name": "Charlie", "age": 35}
]

people = []
for data in people_data:
    person = Person(**data)
    person.greet()
    people.append(person)

for person in people:
    print(f"{person.name} is {person.age} years old.")
