Introduction to Dictionaries in Python

Welcome to "Introduction to Dictionaries in Python" where we explore the fundamentals of dictionaries and their versatile capabilities! 📖
In this tutorial, we'll cover:
- Creating a Dictionary: Techniques for creating dictionaries using curly braces `{}` and key-value pairs.
- Characteristics of Dictionaries: Understanding dictionaries as unordered collections of mutable key-value pairs where keys are unique.
- Ordered (Python 3.7+): Note that dictionaries are ordered starting from Python 3.7.
- Mutable: Dictionaries allow for modification after creation.
- Duplicates Not Allowed: Keys in dictionaries must be unique; attempting to add a duplicate key will overwrite the existing value.
- Length: How to determine the number of key-value pairs in a dictionary using the `len()` function.
- Type: Exploring the data type of dictionaries and their elements.
- `dict()` Constructor: Creating dictionaries using the `dict()` constructor function.
Understanding dictionaries is crucial as they are fundamental for storing and accessing data efficiently in Python programming.
