The basic concept of JSON in Python: Comprehensive Guide
2 min readFeb 28, 2024
JSON (JavaScript Object Notation) is a popular data format commonly used for exchanging data between applications and storing structured information. Python provides a built-in module named json
to work with JSON data. Here's an overview of working with JSON in Python:
1. Importing the json
module:
import json
2. Converting Python objects to JSON:
- Use the
json.dumps()
function to convert a Python object (like dictionaries, lists, numbers, strings, etc.) into a JSON string:
data = {"name": "Alice", "age": 30, "city": "New York"}
json_string = json.dumps(data)
print(json_string) # Output: {"name": "Alice", "age": 30, "city": "New York"}
3. Converting JSON strings to Python objects:
- Use the
json.loads()
function to convert a JSON string back into a Python object:
json_string = '{"name": "Bob", "age": 25, "hobbies": ["reading", "coding"]}'
data = json.loads(json_string)
print(data) # Output: {'name': 'Bob', 'age': 25, 'hobbies': ['reading', 'coding']}
4. Additional functionalities:
- The
json
the module offers various other functionalities like: indent
parameter: Controls the indentation level in the output JSON string (useful for readability).ensure_ascii
parameter: Controls whether to use ASCII characters or Unicode characters in the output (relevant for handling non-English characters).- Encoding and decoding: Allows working with JSON data stored in files using specific encodings.
Remember:
- Python can handle the most common data types when converting between JSON and Python objects.
- For complex custom objects, you might need to implement custom serialization and deserialization logic.
