json.dumps and json.loads

dumps() converts Python objects to JSON strings, while loads() parses JSON strings into Python objects.

dumps - Python to JSON String

Convert Python objects to JSON strings.

import json

data = {
    "name": "Alice",
    "age": 30,
    "hobbies": ["reading", "coding"]
}

# Convert to JSON string
json_str = json.dumps(data)
print(json_str)
print(type(json_str))

{"name": "Alice", "age": 30, "hobbies": ["reading", "coding"]}
<class 'str'>

loads - JSON String to Python

Parse JSON strings into Python objects.

import json

json_str = '{"name": "Bob", "age": 25, "active": true}'

# Parse JSON string
data = json.loads(json_str)
print(data)
print(type(data))
print(f"Name: {data['name']}")
print(f"Active: {data['active']}")

{'name': 'Bob', 'age': 25, 'active': True}
<class 'dict'>
