Serializing JSON data in Python

Serialization is the process of encoding the from naive data type to JSON format. The Python module json converts a Python dictionary object into JSON object, and list and tuple are converted into JSON array, and int and float converted as JSON number, None converted as JSON null.

Let’s take a look at how we serialize Python data to JSON format with these methods:

• Dump().
• Dumps().

json.dump()

json.dump() method can be used for writing to JSON file. Write data to a file-like object in json format.

Syntax: json.dump(dict, file_pointer)

Parameters:

• dictionary – name of dictionary which should be converted to JSON object.
• file pointer – pointer of the file opened in write or append mode.

Below is the implementation:

Converting python object and writing into json file.

Output:

json.dumps()

json.dumps() method can convert a Python object into a JSON string.

Syntax: json.dumps(dict)

Parameters:

• dictionary – name of dictionary which should be converted to JSON object.

Below is the implementation:

Converting python object into json string.

Output:
