json.loads() in Python
JSON stands for JavaScript Object Notation. It is a lightweight data-interchange format that is used to store and exchange data. It is a language-independent format and is very easy to understand since it is self-describing in nature. There is a built-in package in python that supports JSON data which is called as json. The data in JSON is represented as quoted-strings consisting of key-value mapping enclosed between curly brackets {}.
json.loads()
json.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.
Syntax : json.loads(s)
Argument: it takes a string, bytes, or byte array instance which contains the JSON document as a parameter (s).
Return: It returns a Python object.
Example 1:Suppose the JSON string looks like this.
x = """{
"Name": "Jennifer Smith",
"Contact Number": 7867567898,
"Email": "jen123@gmail.com",
"Hobbies":["Reading", "Sketching", "Horse Riding"]
}"""
In order to read the content of this string following implementation needs to be carried out:
import json # JSON string:# Multi-line stringx = """{ "Name": "Jennifer Smith", "Contact Number": 7867567898, "Email": "jen123@gmail.com", "Hobbies":["Reading", "Sketching", "Horse Riding"] }""" # parse x:y = json.loads(x) # the result is a Python dictionary:print(y) |
Output:
{‘Hobbies’: [‘Reading’, ‘Sketching’, ‘Horse Riding’], ‘Name’: ‘Jennifer Smith’, ‘Email’: ‘jen123@gmail.com’, ‘Contact Number’: 7867567898}
Here, the string x is parsed using json.loads() method which returns a dictionary.
Example 2:
import json # JSON string employee ='{"id":"09", "name": "Nitin", "department":"Finance"}' # Convert string to Python dict employee_dict = json.loads(employee) print(employee_dict) print(employee_dict['name']) |
Output:
{'id': '09', 'department': 'Finance', 'name': 'Nitin'}
Nitin
