The json library in Python

1. Encoding Python Data to JSON:

import json

# Python dictionary to be encoded to JSON

data = {

    "name": "John",

    "age": 30,

    "city": "New York"

}

​

# Encode the Python dictionary to JSON

json_data = json.dumps(data)

print("Encoded JSON:", json_data)

#clcoding.com

Encoded JSON: {"name": "John", "age": 30, "city": "New York"}

2. Decoding JSON to Python Data:

import json

​

# JSON data to be decoded to Python

json_data = '{"name": "John", "age": 30, "city": "New York"}'

​

# Decode the JSON data to a Python dictionary

data = json.loads(json_data)

​

print("Decoded Python Data:", data)

​

#clcoding.com

Decoded Python Data: {'name': 'John', 'age': 30, 'city': 'New York'}

3. Reading JSON from a File:

clcoding

import json

​

# Read JSON data from a file

with open('clcoding.json', 'r') as file:

    data = json.load(file)

​

print("JSON Data from File:", data)

​

#clcoding.com

4. Writing JSON to a File:

import json

​

# Python dictionary to be written to a JSON file

data = {

    "name": "John",

    "age": 30,

    "city": "New York"

}

​

# Write the Python dictionary to a JSON file

with open('output.json', 'w') as file:

    json.dump(data, file)

​

    #clcoding.com

5. Handling JSON Errors:

import json

​

# JSON data with syntax error

json_data = '{"name": "John", "age": 30, "city": "New York"'

​

try:

    # Attempt to decode JSON data

    data = json.loads(json_data)

except json.JSONDecodeError as e:

    # Handle JSON decoding error

    print("Error decoding JSON:", e)
