JSON stands for JavaScript Object Notation. JSON is a lightweight format that is used to save and exchange data. The data in JSON is represented as quoted strings consisting of key-value mapping enclosed between curly braces { }.
Python JSON to Dict
To convert Python JSON to dict, use the json.loads() function. The json.loads() is a built-in function that can parse the valid JSON string and convert it into a Dictionary. The loads() function takes a string as a parameter and returns the dictionary.
Syntax
json.loads(str)
Parameters
The loads() function takes str, bytes, or byte array instance, containing the JSON document as parameter str.
Example
To work with json module, import the json module, and then you will be able to use the loads() method.
import json
data = '{ "name":"WandaVision", "service":"Disneyplus", "city":"New York"}'
# parse the data
dict = json.loads(data)
print(dict)
Output
{'name': 'WandaVision', 'service': 'Disneyplus', 'city': 'New York'}
And in the output, we get the dictionary with key-value pairs as elements.
Let’s say that if the json JSON string looks like this, then what will be the output.
data = """{
"name":"WandaVision",
"service":"Disneyplus",
"city":"New York"
}"""
This is a multiline strings with triple quotes. Let’s convert this into a dictionary using the loads() function.
import json
data = """{
"name":"WandaVision",
"service":"Disneyplus",
"city":"New York"
}"""
# parse x:
dict = json.loads(data)
print(dict)
Output
{'name': 'WandaVision', 'service': 'Disneyplus', 'city': 'New York'}
How to Read JSON File in Python
To read a json file in Python, use the json.load() method. Let’s say I have a data.json file in my project directory than to read and print the content on the console, write the following code.
import json
with open("data.json") as f:
data = json.load(f)
print(data)
Output
'data': [{'color': 'red', 'value': '#f00'},
{'color': 'green', 'value': '#0f0'},
{'color': 'blue', 'value': '#00f'},
{'color': 'black', 'value': '#000'}]}
Here, we have used the with statement with open() function to read the json file. Then, the file is parsed using json.load() method which gives us a dictionary named data.
That is it for converting Python json to a dictionary.
