Stream formatted output dumper.
dictdumper
is an open source Python program works as a
stream formatted output dumper. Currently, it supports
following formats:
-
Abstract base class of all dumpers.
-
Dump JavaScript object notation (
JSON
) format file. -
Dump Apple property list (
PLIST
) format file. -
Dump tree-view text (
TXT
) format file. -
Dump extensible markup language (
XML
) file; this is an abstract base class -
Dump JavaScript file using
Vue.js
framework; this class is deprecated due to grammar error.Deprecated since version 0.8.0.
-
class
dictdumper.
JSON
(fname, **kwargs)[source] Bases:
dictdumper.dumper.Dumper
Dump JavaScript object notation (JSON) format file.
>>> dumper = JSON(file_name) >>> dumper(content_dict_1, name=content_name_1) >>> dumper(content_dict_2, name=content_name_2) ............
- Variables
Note
Terminology:
object ::= "{}" | ("{" members "}") members ::= pair | (pair "," members) pair ::= string ":" value array ::= "[]" | ("[" elements "]") elements ::= value | (value "," elements) value ::= string | number | object | array | true | false | null
