The Python built-in json module can only handle Python primitives types that have a direct JSON equivalent (e.g., dictionary, lists, strings, Numbers, None, etc.). So when we try to serialize custom class instance into JSON, we receive a type error. TheClass is not JSON serializable. I...
Thejson.toolmodule provides a simple command line interface to validate and pretty-print JSON objects. 如果未指定可选的infile和outfile参数,则将分别使用sys.stdin和sys.stdout: $echo'{"json": "obj"}'|python -m json.tool{"json": "obj"}$echo'{1.2:3.4}'|python -m json.toolExpecting property...

Python 3.0 adds several new built-in functions and changes the semantics of some existing builtins. Functions that are new in 3.0 such asbin()have simply been added to Python 2.6, but existing builtins haven't been changed; instead, thefuture_builtinsmodule has versions with the new 3.0 se...

In languages such as Python, JSON feels like a first class data type. We used all the operator magic of modern C++ to achieve the same feeling in your code. Check out the examples below and you'll know what I mean. Trivial integration. Our whole code consists of a single header file ...
The module is also self-documented, so within the python interpreter type: import demjson3 help(demjson3) or from a shell command line: pydoc demjson3 The "jsonlint" command script which gets installed as part of demjson3 has built-in usage instructions as well. Just type: jsonlint --...
