姊妹篇：【python】json转成成yaml
json数据

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

code v1

# -- coding:utf-8 --
import json, yaml, osBASE_DIR = os.path.dirname(os.path.abspath(__file__))def jsonToYaml(jsonPath, yamlPath):with open(jsonPath, "r", encoding='utf-8') as f:f_json = json.load(f)with open(yamlPath, "w", encoding='utf-8') as f:f_yaml = yaml.dump(f_json)yaml.dump(yaml.safe_load(f_yaml), f, sort_keys=False)if __name__ == '__main__':jsonPath = "data.json"yamlPath = "data.yaml"jsonPath = os.path.join(BASE_DIR, jsonPath)yamlPath = os.path.join(BASE_DIR, yamlPath)jsonToYaml(jsonPath, yamlPath)

转化后：

转化后发现中文显示不是那么友善，全变成了：\u5317\u4EAC\u8DEF123\u53F7,这种形式；
主要原因：
在PyYAML中，默认的编码是UTF-8，但是如果你的字符串包含非UTF-8字符，比如中文，你可能需要指定一个不同的编码。在你的代码中，你可能需要指定在写入YAML文件时使用的编码是UTF-8，而不是默认的编码。

另外，当你使用 yaml.dump() 时，如果你想要保持中文等非ASCII字符的可读性，你应该使用 default_flow_style=False 参数，这样YAML文件将以块样式编写，而不是流动样式。

修改后的代码：

# -- coding:utf-8 --
import json, yaml, osBASE_DIR = os.path.dirname(os.path.abspath(__file__))def jsonToYaml(jsonPath, yamlPath):with open(jsonPath, "r", encoding='utf-8') as f:f_json = json.load(f)with open(yamlPath, "w", encoding='utf-8') as f:f_yaml = yaml.dump(f_json)# yaml.dump(yaml.safe_load(f_yaml), f, sort_keys=False)# 使用safe_dump以避免潜在的安全风险，除非你完全信任源数据yaml.safe_dump(f_json, f, default_flow_style=False, allow_unicode=True)if __name__ == '__main__':jsonPath = "data.json"yamlPath = "data.yaml"jsonPath = os.path.join(BASE_DIR, jsonPath)yamlPath = os.path.join(BASE_DIR, yamlPath)jsonToYaml(jsonPath, yamlPath)

转换后的结果：
