In this example, we have a dictionarydatathat contains information about a person. We open a file calleddata.jsonin write mode and usejson.dump()to write the data to the file in JSON format. Writing Lists to JSON Files You can also write lists to JSON files in a similar way. Here is...
withopen("person.json","w")asfile:file.write(json_str) 1. 2. 上述代码将JSON字符串写入名为person.json的文件中。 示例代码 importjson person={"name":"John","age":30,"city":"New York"}json_str=json.dumps(person)formatted_json_str=json.dumps(person,indent=2)withopen("person.json","w...
f=open('data.json',)# returnsJSONobjectas# a dictionary data=json.load(f)# Iterating through the json # listforiindata['emp_details']:print(i)# Closing file f.close() 输出: 在这里,我们已使用该open()函数读取JSON文件。然后,使用json.load()提供给我们一个名为data的字典的方法来解析文件。
JSON as Dictionary是指将JSON数据解析为Python中的字典(Dictionary)对象,并通过字典对象来访问和操作JSON数据。 在Python中,可以使用内置的json模块来处理JSON数据。json模块提供了loads()函数,可以将JSON字符串解析为Python对象,其中包括字典对象。 下面是使用JSON as Dictionary的示例代码: 代码语言:txt 复制 import js...
