JSON নিয়ে কাজ করা

import json

user = {'name': 'Sam', 'age': 28, 'active': True}
json_string = json.dumps(user)
print(json_string)
# {"name": "Sam", "age": 28, "active": true}

print(json.dumps(user, indent=2))

json_string = '{"name": "Sam", "age": 28}'
user = json.loads(json_string)
print(user['name'])   # Sam — এখন একটা সাধারণ Python dict

# লেখা
with open('user.json', 'w') as f:
    json.dump(user, f, indent=2)

# পড়া
with open('user.json') as f:
    user = json.load(f)

try:
    data = json.loads('{invalid json}')
except json.JSONDecodeError as e:
    print(f'Invalid JSON: {e}')
