JSON要求只有一个根元素。列表或字典可以完成这个角色。JSON要求用双引号括住字符串和名称。JSON中不允许使用单引号。 JSON文件总是合法的JavaScript语法。JSON通常也和Python代码一样有效,如下面的Python程序所示。 jsonHardCoded = { "firstName": "John", "lastName": "Smith", "isAlive": True, "age": 27...

This feature can be used to implement custom decoders (e.g. JSON-RPC class hinting). ``object_pairs_hook`` is an optional function that will be called with the result of any object literal decoded with an ordered list of pairs. The return value of ``object_pairs_hook`` will be used...
Thejson.dumps()function can handle more complex data structures as well, such as nested lists or dictionaries. Let’s take a look at an example: importjson data={"name":"John Doe","age":30,"languages":["Python","JavaScript","Java"],"address":{"street":"123 Main St","city":"New...

The separators parameter for json.dumps() allows you to define a tuple with two values: The separator between the key-value pairs or list items. By default, this separator is a comma followed by a space (", "). The separator between the key and the value. By default, this separator ...
# I have a list of dictionaries. # I want to convert this list into a json object. # I am using the json.dump() function to dump my list into a json file. # I have my code below import json # Convert lists to json object ...
In this case the returned value will be a python dictionary, a list of dictionaries, or even a lazy iterable of dictionaries instead of JSON:>>> import subprocess >>> import jc >>> >>> cmd_output = subprocess.check_output(['dig', 'example.com'], text=True) >>> data = jc.parse...
