Python Dictionaries: Correct Format Explained

In Python, dictionaries are unordered collections of items that are used to store key-value pairs. They are defined using curly braces {} with key-value pairs separated by a colon : and each pair separated by a comma ,. Below are the correctly formatted Python dictionaries:

Correct Python Dictionaries:

1. dict = {'Name': 'Matthew', 'Age': 14, 'School': 'ABC School'};

2. dict = {'season': 'fall', 'weather': 'cool'};

The first two options correctly use curly braces to define dictionaries. The keys and values are separated by colons and each key-value pair is separated by a comma. On the other hand, the third and fourth options are lists, not dictionaries, as they use square brackets [] instead of curly braces {}. The fifth option is also not correctly formatted as it has a single quote before the first square bracket.

To create a Python dictionary, you need to make sure to use the correct syntax with curly braces, colons, and commas as shown in the examples above. Understanding how to work with dictionaries is essential for storing and manipulating data efficiently in Python programming.
