Introduction
What is JSON
4. What data types are used in JSON?
Summary

Instruction

Have another look at our example:

{
"first_name": "Guido",
"last_name": "van Rossum",
"titles": ["BDFL", "Developer"],
"age": 63,
"married": true
}


A JSON file can store a variety of data types:

• Objects are name-value pairs that are placed inside curly braces ({}) and correspond to Python dictionaries.
• Arrays are placed inside brackets ([]) and correspond to Python lists.
• Strings are placed inside a pair of double quotes (e.g., "Guido").
• Numbers must be either an integer or a floating-point value.
• Logical values are either true or false and correspond to the Python values of True and False, respectively.
• null in JSON represents "no value" and corresponds to None in Python.

Each JSON data type corresponds to a Python data type. We'll learn how to transfer information between the two languages later in this course.
