在Python中，我们可以使用json.dumps()函数将Python对象转换回JSON格式，并通过设置参数美化输出，例如增加缩进和换行：# 将Python对象格式化输出为JSON字符串formatted_data = json.dumps(data, indent=4, sort_keys=True)# 写入文件或直接打印输出with open('formatted_data.json', 'w') as file: file.write...
importjson# 读取原始的json文件withopen('data.json','r')asfile:data=json.load(file)# 格式化数据formatted_data=json.dumps(data,indent=4)# 写入新的json文件withopen('formatted_data.json','w')asfile:file.write(formatted_data)print("数据格式化完成!") 1. 2. 3. 4. 5. 6. 7. 8. 9. 10...
print(formatted_json)# 打印格式化后的JSON字符串 1. 如果你想将格式化后的数据写入新文件,可以使用以下代码: withopen('formatted_data.json','w',encoding='utf-8')asformatted_file:formatted_file.write(formatted_json)# 将格式化后的JSON字符串写入新文件 1. 2. 小结 以上就是使用Python打开文件并格式化J...
json_string = None with open("json_file.json") as f: json_string = f.read() try: parsed_json = json.loads(json_string) formatted_json = json.dumps(parsed_json, indent = 4,sort_keys=True) with open("json_file.json","w") as f: f.write(formatted_json) except Exception as e: ...
四. json.dump() 官方解释: """Serialize ``obj`` as a JSON formatted stream to ``fp`` (a ``.write()``-supporting file-like object). 两个字“编码”,写入json文件,例如: with open("number.json","a",encoding="utf-8") as f: ...
def read_json(self): """ 读取json文件,并返回解析后的对象 :return: """ with open(self.file_path,'r') as file: data =json.load(file) return data def write_json(self,data): """ 将python对象转换为json格式,并写入到文件中 如果是原始文件操作则直接替换了之前的所有内容,所以适合写新的json...
# write json data into file json.dump(person_data, file_write) 输出: 无需显示...在您的系统中创建了json_file.json,您可以检查该文件。 JSON到Python(解码) JSON字符串解码是在Python的JSON库的内置方法load()和load()的帮助下完成的。这里的转换表显示了Python对象的JSON对象示例,这些对象有助于在Python...
