你能给我解释一下这段代码吗？(联系人列表)

class Contact:
    def __init__(self, name, phone, email):
        self.name = name
        self.phone = phone
        self.email = email

class ContactList:
    def __init__(self):
        self.contacts = []

    def add_contact(self, contact):
        self.contacts.append(contact)

    def remove_contact(self, contact):
        self.contacts.remove(contact)

    def get_all_contacts(self):
        return self.contacts

# 创建联系人对象
contact1 = Contact("John Doe", "1234567890", "john.doe@example.com")
contact2 = Contact("Jane Smith", "0987654321", "jane.smith@example.com")

# 创建联系人列表对象
contact_list = ContactList()

# 添加联系人到列表
contact_list.add_contact(contact1)
contact_list.add_contact(contact2)

# 获取所有联系人
all_contacts = contact_list.get_all_contacts()

# 打印联系人信息
for contact in all_contacts:
    print("Name: ", contact.name)
    print("Phone: ", contact.phone)
    print("Email: ", contact.email)
    print("--------------------")
