Deserialize JSON to Object in Python

Let us see how to deserialize a JSON document into a Python object. Deserialization is the process of decoding the data that is in JSON format into native data type. In Python, deserialization decodes JSON data into a dictionary(data type in python).
We will be using these methods of the json module to perform this task : 
 

• loads() : to deserialize a JSON document to a Python object.
• load() : to deserialize a JSON formatted stream ( which supports reading from a file) to a Python object.

Example 1 : Using the loads() function. 
 

# importing the module import json # creating the JSON data as a string data = '{"Name" : "Romy", "Gender" : "Female"}' print("Datatype before deserialization : " + str(type(data))) # deserializing the data data = json.loads(data) print("Datatype after deserialization : " + str(type(data))) 

Output : 
 

Datatype before deserialization : Datatype after deserialization : 

Example 2 : Using the load() function. We have to deserialize a file named file.json. 
 

# importing the module import json # opening the JSON file  data = open('file.json',) print("Datatype before deserialization : " + str(type(data))) # deserializing the data data = json.load(data) print("Datatype after deserialization : " + str(type(data))) 

Output : 
 

Datatype before deserialization : Datatype after deserialization :
