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)
