What Is a Dictionary in Python?

Give Feedback

Dictionaries are Python’s implementation of a data structure that is more generally known as an associative array. A dictionary consists of a collection of key-value pairs. Each key-value pair maps the key to its associated value.

You can define a dictionary by enclosing a comma-separated list of key-value pairs in curly braces ({}). A colon (:) separates each key from its associated value:

d = {
    <key>: <value>,
    <key>: <value>,
    <key>: <value>

From Python 3.7, Dictionary order is guaranteed to be insertion order.

Before Python 3.6, we have to use OrderedDict from collections module.

Am i correct here ?

Thank you Paul
