如何在没有命名空间的情况下将类导出到xml？

import xml.etree.ElementTree as ET

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

# 创建一个Person对象
person = Person("John Doe", 30)

# 创建根元素
root = ET.Element("Person")

# 创建子元素并设置属性
name_element = ET.SubElement(root, "Name")
name_element.text = person.name

age_element = ET.SubElement(root, "Age")
age_element.text = str(person.age)

# 创建XML树
tree = ET.ElementTree(root)

# 将XML保存到文件
tree.write("person.xml")
