【python】yaml转成json

姊妹篇：【python】json转成成yaml

yaml数据：

address:
  city: 北京市
  postalCode: '100000'
  street: 北京路123号
age: 30
cart:
- product:
    name: 笔记本电脑
    price: 1199.99
    quantity: 2
- product:
    name: 智能手机
    price: 599.99
    quantity: 1
children:
- age: 5
  name: 小王
- age: 3
  name: 小李
email: zhangsan@example.com
isMarried: false
login:
  password: password123
  username: zhangsan
name: 张三
phoneNumbers:
- number: '2341234'
  type: home
- number: '5678901'
  type: office

实现代码：

# -- coding:utf-8 --
import yaml
import json
import os

BASE_DIR = os.path.dirname(os.path.abspath(__file__))


def yamlTojson(yaml_path, json_path):
    # 读取YAML文件
    with open(yaml_path, 'r', encoding='utf-8') as stream:
        try:
            # 将YAML内容转换为Python字典
            data_yaml = yaml.safe_load(stream)

            # 将Python字典转换为JSON字符串
            data_json = json.dumps(data_yaml, ensure_ascii=False, indent=4)

            # 将JSON字符串写入到JSON文件
            with open(json_path, 'w', encoding='utf-8') as f:
                f.write(data_json)

            print(f"YAML文件'{yaml_path}'已成功转换为JSON文件'{json_path}'")
        except yaml.YAMLError as exc:
            print(f"YAML文件解析错误： {exc}")


if __name__ == '__main__':
    jsonPath = "data2.json"
    yamlPath = "data.yaml"
    jsonPath = os.path.join(BASE_DIR, jsonPath)
    yamlPath = os.path.join(BASE_DIR, yamlPath)
    yamlTojson(yamlPath, jsonPath)

结果展示：
