How to Read and Write JSON Files in Python

4/6 What data types are used in JSON?

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.

True or False: Answer by assigning True or False to the variable below the given statement.
