The correct answer is A. key-value pairs.<\/p>\n
A dictionary is a data structure that maps keys to values. The keys are unique identifiers for the values, and the values can be any type of data. Dictionaries are often used to store data in a way that is easy to access and search.<\/p>\n
Here is an example of a dictionary:<\/p>\n
In this example, the keys are “name”, “age”, and “address”.

For example, the following code creates a dictionary with two keys and two values:<\/p>\nmy_dictionary = {\"name\": \"John Doe\", \"age\": 30}<\/code><\/p>\n[]<\/code> syntax. For example, the following code prints the value of the “name” key:<\/p>\nprint(my_dictionary[\"name\"])<\/code><\/p>\n[]=<\/code> syntax. For example, the following code updates the value of the “age” key to 31:<\/p>\nmy_dictionary[\"age\"] = 31<\/code><\/p>\ndel<\/code> keyword. For example, the following code deletes the “name” key:<\/p>\ndel my_dictionary[\"name\"]<\/code><\/p>\nKeyError: \"name\"<\/code>.<\/p>\n
