What is a JSON dumps?

The json. dumps() method allows us to convert a python object into an equivalent JSON object. Or in other words to send the data from python to json. The json. dump() method allows us to convert a python object into an equivalent JSON object and store the result into a JSON file at the working directory.

What is the difference between JSON load and loads?

The json. load() is used to read the JSON document from file and The json. loads() is used to convert the JSON String document into the Python dictionary. fp file pointer used to read a text file, binary file or a JSON file that contains a JSON document.

What type is JSON dumps?

dumps() in Python. The full-form of JSON is JavaScript Object Notation. It means that a script (executable) file which is made of text in a programming language, is used to store and transfer the data.

What are JSON loads?

loads() method can be used to parse a valid JSON string and convert it into a Python Dictionary. It is mainly used for deserializing native string, byte, or byte array which consists of JSON data into Python Dictionary.


dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

json loads -> returns an object from a string representing a json object.

json dumps -> returns a string representing a json object from an object.

load and dump -> read/write from/to file instead of string
