Dictionaries in Python? | Straightforward Python

In this article, you’ll learn everything about Python dictionaries; how they are created, accessing, adding, removing elements from them and various built-in methods.

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

thisdict = {
  "brand": "Apple",
  "model": "iPhone 12 pro",
  "year": 2020
}

Creating Python Dictionary

Creating a dictionary is as simple as placing items inside curly braces {} separated by commas as stated above

An item has a key and a corresponding value that is expressed as a pair (key: value).

Create and print a dictionary:

thisdict = {
  "brand": "Apple",
  "model": "iPhone 12 pro",
  "year": 2020
}
print(thisdict)
