Convert JSON to dictionary in Python

Last Updated : 29 Dec, 2020

JSON stands for 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. Python supports JSON through a built-in package called json. To use this feature, we import the json package in Python script. The text in JSON is done through quoted-string which contains value in key-value mapping within { }. It is similar to the dictionary in Python.

Function Used:

json.load(): json.loads() function is present in python built-in ‘json’ module. This function is used to parse the JSON string.
Syntax: json.load(file_name)
Parameter: It takes JSON file as the parameter.
Return type: It returns the python dictionary object.

Example 1: Let’s suppose the JSON file looks like this:

python-json

We want to convert the content of this file to Python dictionary. Below is the implementation.

# Python program to demonstrate
# Conversion of JSON data to
# dictionary
  
  
# importing the module
import json
  
# Opening JSON file
with open('data.json') as json_file:
    data = json.load(json_file)
  
    # Print the type of data variable
    print("Type:", type(data))
  
    # Print the data of dictionary
    print("\nPeople1:", data['people1'])
    print("\nPeople2:", data['people2'])

Output :

python-json

Example 2: Reading nested data
In the above JSON file, there is a nested dictionary in the first key people1. Below is the implementation of reading nested data.

# Python program to demonstrate
# Conversion of JSON data to
# dictionary
  
  
# importing the module
import json
  
# Opening JSON file
with open('data.json') as json_file:
    data = json.load(json_file)
  
    # for reading nested data [0] represents
    # the index value of the list
    print(data['people1'][0])
      
    # for printing the key-value pair of
    # nested dictionary for looop can be used
    print("\nPrinting nested dicitonary as a key-value pair\n")
    for i in data['people1']:
        print("Name:", i['name'])
        print("Website:", i['website'])
        print("From:", i['from'])
        print()

Output :

python-json
