json.dumps() - Dumping Object into JSON
How to dump (or encode, serialize) a Python object into a JSON string using json.dumps()?
✍: FYIcenter.com
The json.dumps() function allows you to dump (or encode, serialize) Python objects into JSON strings:
json.dumps(obj, *, skipkeys=False, ensure_ascii=True, check_circular=True, allow_nan=True, cls=None, indent=None, separators=None, default=None, sort_keys=False, **kw)
The json.dumps() functions uses the following default encoding table:
Python Type JSON Type ----------- --------- dict object list array tuple array str string int number float number int- number float-derived Enums number True true False false None null
Some examples on using the json.dumps() function:
>>> import json >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}]) '["foo", {"bar": ["baz", null, 1.0, 2]}]' >>> print(json.dumps("\"foo\bar")) "\"foo\bar" >>> print(json.dumps('\u1234')) "\u1234" >>> print(json.dumps('\\')) "\\" >>> print(json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)) {"a": 0, "b": 0, "c": 0}
If you try to dump an object that is not supported with json.dumps(), you will get the "Object of type '...' is not JSON serializable" error:
>>> import json >>> json.dumps(json) Traceback (most recent call last): File "C:...\Python36-32\lib\json\__init__.py", line 231, in dumps return _default_encoder.encode(obj) ... TypeError: Object of type 'module' is not JSON serializable
