params: ArgumentSpec property

Keyword parameter information.

This is a forward compatible alias for :attr:args.

args(spec)

Information about accepted arguments.

It would be more correct to use term parameter instead of argument in this context, and this attribute may be renamed accordingly in the future. A forward compatible :attr:params attribute exists already now.

Create this object based on JSON data.

The data is given as the source parameter. It can be:

The JSON data is first converted to a Python dictionary and the object created using the :meth:from_dict method.

Notice that the source is considered to be JSON data if it is a string and contains {. If you need to use { in a file system path, pass it in as a pathlib.Path instance.

Serialize this object into JSON.

The object is first converted to a Python dictionary using the :meth:to_dict method and then the dictionary is converted to JSON.

The file parameter controls what to do with the resulting JSON data. It can be:

  • None (default) to return the data as a string,
  • an open file object where to write the data to, or
  • a path (pathlib.Path or string) to a file where to write the data using UTF-8 encoding.

JSON formatting can be configured using optional parameters that are passed directly to the underlying json__ module. Notice that the defaults differ from what json uses.
