Step 1: Load JSON data First, you need to load the JSON data into a Python object. This can be done using thejsonmodule’sloads()function. importjson json_data='{"name": "John", "age": 30, "city": "New York"}'d

#3.ensure_ascii:,当它为True的时候,所有非ASCII码字符显示为\uXXXX序列,只需在dump时将ensure_ascii设置为False即可,此时存入json的中文即可正常显示。)#If check_circular is false, then the circular reference check for container types will be skipped and a circular reference will result in an OverflowE...
- 重写JSONEncoder类的default方法。 使用示例: import json class Article(): def __init__(self, title, author, url): self.title = title self.author = author self.url = url # 自定义Encoder类 class ArticleEncoder(json.JSONEncoder): def default(self, obj): if isinstance(obj, Article): ret...

json模块中常用的函数和类的功能如下。 json.dump(obj, fp, *, skipkeys=False, ensure_ascii=True, check_circular=True, allow_nan= True, cls=None, indent=None, separators=None, default=None, sort_keys=False, **kw):将obj对象转换成JSON字符串输出到fp流中,fp是一个支持write()方法的类文件对象...
