Dictionaries and Sets: Efficient Data Retrieval # Welcome back to our programming tutorial series! Today, we’ll explore two powerful data structures in Python: dictionaries and sets. These structures allow you to store and retrieve data efficiently, especially when working with unique values or key-value pairs.
What Are Dictionaries? # A dictionary is an unordered collection of key-value pairs, where each key is unique. You can use a dictionary to store related pieces of information and access them using the corresponding key.

Welcome back to our programming tutorial series! Today, we’re diving into arrays and lists, fundamental data structures that allow you to store and manipulate collections of data efficiently. While Python doesn’t have a built-in array type, it offers lists which serve a similar purpose and are more flexible.
What are Lists? # In Python, a list is an ordered collection of items. These items can be of any type - numbers, strings, or even other lists.
