使用respond_with返回xml,json等格式化的多个变量和数组的最佳方法是什么

import json
from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/data')
def get_data():
    data = {
        'name': 'John',
        'age': 30,
        'cities': ['New York', 'Los Angeles', 'Chicago']
    }
    return jsonify(data)

if __name__ == '__main__':
    app.run()

import xml
from flask import Flask, request, xmlify

app = Flask(__name__)

@app.route('/data')
def get_data():
    data = {
        'name': 'John',
        'age': 30,
        'cities': ['New York', 'Los Angeles', 'Chicago']
    }
    return xmlify(data)

if __name__ == '__main__':
    app.run()
