Hello, tireless coders! Are you prepared for another Python adventure? Today’s topic is ‘JSON’ - JavaScript Object Notation. JSON is a lightweight data exchange format that is simple for humans to read and write while also being simple for machines to parse and generate. It is used to send data from a server to a web page. To work with JSON data, the Python standard library includes a **‘json’ **module capable of parsing JSON from strings or files and converting them to Python dictionaries. Python dictionaries can also be converted into JSON strings. Consider this simple JSON data:
{
"name": "John",
"age": 30,
"city": "New York"
}
We can convert this JSON data to a Python dictionary like this:
import json
json_data = '{"name": "John", "age": 30, "city": "New York"}'
python_dict = json. loads(json_data)
print(python_dict) # Output: {'name': 'John', 'age': 30, 'city': 'New York'}
Exercise
- Write a Python program that reads the above JSON data and converts it into a Python dictionary.
- Modify some values of this dictionary and write it back as a JSON string.
Conclusion
Voila! You have now learned how to use JSON data in Python. It’s a useful tool to have, especially when working with web data. Continue to explore and code. Remember that each step you take brings you closer to learning Python. Continue, courageous coder!
