Is there any way to have python's json.dumps(<val>) output in minified form? (i.e. get rid of extraneous spaces around commas, colons etc.)

json. dump() method used to write Python serialized object as JSON formatted data into a file. json. dumps() method is used to encodes any Python object into JSON formatted String.
The dump() method is used when the Python objects have to be stored in a file. The dumps() is used when the objects are required to be in string format and is used for parsing, printing, etc, . The dump() needs the json file name in which the output has to be stored as an argument.
dumps() json. dumps() function converts a Python object into a json string. skipkeys:If skipkeys is true (default: False), then dict keys that are not of a basic type (str, int, float, bool, None) will be skipped instead of raising a TypeError.
The default is (', ', ': ') if indent is None and (',', ': ') otherwise. To get the most compact JSON representation, you should specify (',', ':') to eliminate whitespace.
You should set the separators parameter:
>>> json.dumps([1, 2, 3, {'4': 5, '6': 7}], separators=(',', ':')) '[1,2,3,{"4":5,"6":7}]' From the docs:
If specified, separators should be an
(item_separator, key_separator)tuple. The default is(', ', ': ')if indent isNoneand(',', ': ')otherwise. To get the most compact JSON representation, you should specify(',', ':')to eliminate whitespace.
