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: 1199.99quantity: 2
- product:name: 智能手机price: 599.99quantity: 1
children:
- age: 5name: 小王
- age: 3name: 小李
email: zhangsan@example.com
isMarried: false
login:password: password123username: 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 osBASE_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：
