Convert JSON to dictionary in Python
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:
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 moduleimport json # Opening JSON filewith 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 :
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 moduleimport json # Opening JSON filewith 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 :
