如何使用Python和百度地图API进行地图标注点的添加和编辑？

import requests

def add_marker(lng, lat, label):
    url = "http://api.map.baidu.com/geoconv/v1/?coords=" + str(lng) + "," + str(lat) + "&from=1&to=5&ak=your_api_key"
    response = requests.get(url)
    result = response.json()
    converted_lng = result['result'][0]['x']
    converted_lat = result['result'][0]['y']

    url = "http://api.map.baidu.com/trace/v2/track/addpoint"
    data = {
        "ak": "your_api_key",
        "service_id": "your_service_id",
        "point_list": converted_lng + "," + converted_lat + ";" + label,
        "coord_type_output": "bd09ll"
    }
    response = requests.post(url, data=data)
    result = response.json()

    if result['status'] == 0:
        print("标注点添加成功！")
    else:
        print("标注点添加失败！")

if __name__ == "__main__":
    lng = 116.404
    lat = 39.915
    label = "这是一个标注点"

    add_marker(lng, lat, label)

import requests

def update_marker(point_id, new_label):
    url = "http://api.map.baidu.com/trace/v2/track/updatepoint"
    data = {
        "ak": "your_api_key",
        "service_id": "your_service_id",
        "point_id": point_id,
        "point_list": new_label
    }
    response = requests.post(url, data=data)
    result = response.json()

    if result['status'] == 0:
        print("标注点编辑成功！")
    else:
        print("标注点编辑失败！")

if __name__ == "__main__":
    point_id = "your_point_id"
    new_label = "这是修改后的标注点"

    update_marker(point_id, new_label)
