JSON in Python (P1)

Tram Ho

1. What is JSON?

JSON is a data format that uses plain text, JSON format uses key-value pairs for the data to use. JSON was originally developed for use in JavaScript applications. The JSON term itself stands for JavaScript Object Notation. However, since JSON is a data format, it can be used by any language without limitation with JavaScript.

2. JSON in Python

Python has a built-in caller called json that can be used to work with JSON data.

1. Convert JSON in Python

Use the json.loads() function to convert a JSON string to Dictionary

2. Convert the Python object to JSON

3. Format display

For a nice display, it is easier to see json.dumps() provides an additional indent parameter to format the indent number (1 indent equals 1 space)

4. Arrange the key

By default JSON will display the keys out of order. To sort keys, json.dumps() provides the sort_keys parameter

3. Conclusion
