原始csv

# encoding:utf-8
import requests
import csv
import json
# 接口地址
url = "https://api.map.baidu.com/geocoding/v3"

# 此处填写你在控制台-应用管理-创建应用后获取的AK
ak = "XXXXXXX"

# 创建CSV文件并写入数据
with open('output22.csv', 'w', encoding='utf-8', newline='') as file:
    # 创建CSV写入器
    writer = csv.writer(file)

# 打开CSV文件
with open(r"D:\000datasets\链家房价数据\2020去重后社区名称.csv", 'r', encoding='utf-8') as file:
    # 创建CSV读取器
    reader = csv.reader(file)

    # 遍历每一行数据
    for row in reader:
        # 打印每一行数据
        # print(row[0],type(row[0]))
        params = {
            "address":    row[0],
            "output":    "json",
            "ak":       ak,

        }

        response = requests.get(url=url, params=params)
        if response:
            # print(response.json()['status'],type(response.json()['status']))
            if response.json()['status']==0:
                # print("True")
                print(response.json())    #{'status': 0, 'result': {'location': {'lng': 116.3076223267197, 'lat': 40.05682848596073}, 'precise': 1, 'confidence': 80, 'comprehension': 100, 'level': '门址'}}
                json_str = json.dumps(response.json())
                parsed_data = json.loads(json_str)
                # print(parsed_data, type(parsed_data))
                # 获取指定字段的内容
                lng = parsed_data['result']["location"]["lng"]
                lat = parsed_data['result']["location"]["lat"]

                # 创建CSV文件并写入数据
                with open('output22.csv', 'a', encoding='utf-8', newline='') as file:
                    # 创建CSV写入器
                    writer = csv.writer(file)
                    writer.writerow([row[0],lng,lat,parsed_data['result']['precise'],parsed_data['result']['confidence'],parsed_data['result']['comprehension'],parsed_data['result']['level']])

结果：
