如何在id上合并2个字典并将它们写入到一个xml文件中

import xml.etree.ElementTree as ET

def merge_dicts(dict1, dict2):
    merged_dict = dict1.copy()
    merged_dict.update(dict2)
    return merged_dict

def dict_to_xml(dictionary, root_name):
    root = ET.Element(root_name)
    for key, value in dictionary.items():
        sub_element = ET.SubElement(root, key)
        sub_element.text = str(value)
    return ET.tostring(root, encoding='utf-8')

dict1 = {'name': 'John', 'age': 25}
dict2 = {'city': 'New York', 'country': 'USA'}

merged_dict = merge_dicts(dict1, dict2)
xml_data = dict_to_xml(merged_dict, 'data')

with open('output.xml', 'wb') as f:
    f.write(xml_data)
